For God so loved the Cosmos

For God so Loved the Cosmos- John 3:1-17 & Matthew 5:21–37

On this 2nd Sunday of Lent, the lectionary gives us words from John’s Gospel: the mysterious nighttime conversation between Jesus and Nicodemus.

We read well-know words: “Unless one is born from above/anew, one cannot see the kingdom of God.”  And then those words so often quoted: “For God so loved the world…”

But we’ll come back to these words from John’s Gospel.

In addition to the Lectionary readings over Lent that come from John’s Gospel, I would also during this Lenten season like to reflect intentionally on the Sermon on the Mount from Gospel of Matthew. And at first glance, John and Matthew feel very different. John speaks of new birth, Spirit, eternal life, cosmic love. Matthew gives us teachings on anger, lust, divorce, and taking oaths.

But what if they are describing the same transformation from two different angles? John tells us where transformation begins. Matthew shows us what transformation looks like. To be “born from above” or “being born again” is not a religious slogan. It is the awakening of the inner life. And in Matthew 5, Jesus shows us what that awakened life looks like in practice.

Importantly, when we open Matthew’s Gospel, we are not simply reading a biography of Jesus. We are entering a school of discipleship. Matthew’s Gospel functions almost like the earliest catechism of the Church, a manual for forming people in the way of Christ. And this becomes unmistakably clear at the very end of the Gospel, when the risen Jesus says:

“Go therefore and make disciples… teaching them to obey everything I have commanded you.”  That final sentence tells us why Matthew wrote. This Gospel is not merely to inform us about Jesus. It is to form us by Jesus. And at the heart of this formation stands the Sermon on the Mount.

Matthew structures his Gospel around five great teaching blocks, five great discourses (see below), echoing the five books of Moses. And Matthew is deliberately telling us something through that structure. Just as Moses gave Torah to Israel, Jesus now gives teaching, a new Torah to a renewed people.

So when we come to Matthew 5:21–37, we are not just picking up a handful of moral sayings about anger and divorce and oaths. We are stepping into Matthew’s curriculum for discipleship.

But whereas Moses says, “Thus says the Lord,” In Matthew’s Gospel Jesus says, “But I say to you.” This is breathtaking. Jesus talks with greater authority than Moses. Matthew’s Jesus is not rejecting Judaism. He is portraying Jesus as revealing the deepest intention of Torah. And what is that deepest intention? Not mere rule-keeping, but transformation of the heart.

In today’s passage we hear six times: “You have heard that it was said… but I say to you…” And as he does so, murder becomes anger, adultery becomes lust, divorce becomes covenant faithfulness and oaths become simple truthfulness.

At first glance it sounds as though Jesus is making the law harsher. But that is not what is happening. This is not intensification. It is interiorisation. Jesus moves righteousness from external compliance to inner transformation.

Murder destroys life, but anger and contempt destroy relationships long before blood is shed. Adultery breaks a relationship. But a gaze that turns another person into an object fractures love at its root. Oaths were designed to guarantee truthfulness. But Jesus calls for a life so integrated that no oath is necessary. Let your “yes” be yes and let you “no” be no.

The movement is always the same: From behaviour, to the heart, to relational wholeness. This is why in John’s Gospel Jesus speaks of a transformation of the heart, a rebirth of our inner life. Because anger, lust and dishonesty cannot ultimately be managed merely by external restraint. Something in us must be made new. Nicodemus knew the Law. But knowing the Law is not the same as being inwardly renewed. And so in Matthew, the Sermon on the Mount assumes rebirth. It assumes a heart being reshaped.

|As we saw 2 weeks ago, just before this passage in Matthew, Jesus says: “Unless your righteousness exceeds that of the scribes and Pharisees, you will not enter the kingdom of heaven.”  That sounds intimidating, until we understand what Matthew means by righteousness. Righteousness here is not legal precision. It is alignment with the heart of God.

And that alignment culminates later in this chapter: “Be perfect as your Father in heaven is perfect.” “Perfect” does not mean flawless. It means being made whole, mature, integrated. It is the perfection of a love that shines on good and bad alike.

Matthew’s Jesus is not primarily a miracle worker in this Gospel. He is the teacher of divine wisdom and the revealer of the Father’s character. And he is forming people who reflect the heart of God.

But notice how in Matthew, community is the place of salvation. Notice how relational this passage is: Be reconciled before you bring your gift to the altar. Settle matters quickly. Let your speech be truthful.

For Matthew, salvation is not merely private forgiveness. It is the formation of a reconciled community. In Matthew, worship without reconciliation is incomplete. Discipleship is the formation of a reconciled and a reconciling community. And later on in chapter 18, Matthew will expand this vision: how to deal with conflict, how to forgive, how to live together.  The church is meant to embody a new kind of humanity.

But this vision of a reconciled community is not just limited to individuals or even the church. John’s Gospel speaks of God’s Love for the world. In fact the Greek word is ‘kosmos’. For God so loved the world… for God so loved the Kosmos. God’s saving renewing love according to John’s Gospel includes not just individual human souls but the whole world. A cosmic love that embraces the entire Kosmos. Those who experience a rebirth from within begin to share in the Kosmic love of God. Transformed individuals begins to transform the world because their hearts are aflame with a Love for the whole Ksomos.

And this renewal begins as an inward reality. The “Kingdom of Heaven” in Matthew’s Gospel begins in the heart.. and what does that kingdom look like according to Matthew’s Jesus?

Not simmering resentment. Not objectifying desire. Not manipulative speech. The kingdom is not first a political revolution. It is transformed heart, a transformed, consciousness that leads to healed relationships and then radiates outward. It is what happens when the law moves from tablets of stone to the depths of the heart.

So what does this reveal about Matthew’s perspective on the Jesus story?

It tells us that for Matthew:

• Jesus is the definitive interpreter of Torah.
• Discipleship means obedience to his teaching.
• Obedience means interior transformation.
• Interior transformation creates reconciled community.
• And reconciled community embodies the Kingdom.

The Jesus story according to Matthew is not merely about the cancellation of guilt. It is about the creation of a new humanity.

And so the question for us is not, “Have I avoided murder?” but “What is happening in my heart toward my brother or sister?” Not, “Have I technically kept the rule?”
but “Is my life becoming whole, is my life radiating Divine Love?”

The Sermon on the Mount is not optional spirituality. It is the shape of Christian maturity. It is the slow, patient work of allowing Christ to transform not just our actions, but our perception, our desires, our speech, and our relationships. And in that transformation, the Kingdom comes.

In closing we return to Nicodemus.

He comes to Jesus at night, curious, cautious, not yet seeing clearly. And Jesus speaks to him of birth from above. Inner renewal of the heart.

Perhaps that is what Lent is for. Not moral tightening. Not religious anxiety. But allowing God to bring forth new life at the root of our being.

And why? Because “God so loved the kosmos.” Not just me. Not just you. Not even just this whole tangled, wounded, yet beautiful world, but the whole create order.

The Sermon on the Mount shows us the shape of that love lived out: anger relinquished, contempt healed, desire purified, speech made simple and true

And when that happens, even imperfectly, the kosmos begins to look, in some small way, as God intends it to be. Amen.
