Psalm 65:4–13, Matthew 6: 25–34

By Revd George Mwaura

In our reading this morning, the psalmist praises the Creator whose generosity sustains the earth – listen: ‘The river of God is full of water. The pastures of the wilderness overflow. The valleys deck themselves with grain.’ Creation in this psalm is not silent. It sings. It rejoices. It bears witness to the goodness of God. Then in the Gospel of Matthew, Jesus invites us to learn from creation itself, listen again: ‘Look at the birds of the air. Consider the lilies of the field.’ Here, the birds preach a sermon on trusting God; the lilies proclaim beauty without anxiety. Nature becomes a living parable of God’s care.

Today, however, we hear these readings in a world where creation is groaning. The earth is speaking – in heatwaves, droughts, floods and fires – yet too many people still refuse to listen. A week ago, temperatures in the United Kingdom reached 35.1 C! while Pakistan recorded a whooping 49.5 C! And still, someone interviewed in Wales casually and carelessly said, ‘If this is global warming, bring it on.’ What a tragedy it is when comfort blinds us to suffering beyond our own doorstep. For one person, heat may feel like a pleasant summer. For another, it means failed crops, displacement, sickness, and death. Climate change is not entertainment; it is a warning. The poorest communities, those who contributed least to this crisis, are often those who suffer first and most. World Environment Sunday therefore calls us not only to protect the planet, but also to recover our humanity, to recognise that we share one fragile home, one atmosphere, and one future together. The question is no longer whether the world is changing; that it is. The question is whether we will change in time. So, what does it mean to mark World Environment Sunday as followers of Christ?

First, it means remembering that creation belongs to God. The earth is not simply a resource to exploit or a warehouse of commodities. The forests belong to God. The oceans belong to God. The atmosphere belongs to God. Human beings are not absolute owners of the earth; we are stewards of a sacred gift. The abundance of the earth is sustained not merely by human effort but by divine grace. Rainfall is grace. Harvest is grace. Biodiversity is grace. The beauty of creation is grace. And because creation is a gift, it must never be treated carelessly.

Second, these readings challenge the culture of fear and excess that drives environmental destruction. When Jesus says, do not worry, he is not dismissing responsibility; he is confronting the fear and greed that lead to endless accumulation. Much of the ecological crisis today is fuelled by the belief that there is never enough. Nations and individuals consume recklessly. Corporations exploit endlessly. People are taught that happiness comes through possession and consumption. But Jesus points us toward another way. The birds survive without storing wealth. The lilies bloom without striving for status. Creation reveals a divine economy based, not on greed, but on trust and sufficiency. We must reject the false gospel of endless consumption and rediscover simplicity, gratitude, and responsible living.

Third, caring for creation is part of Christian discipleship. From Genesis to Revelation, scripture declares God’s love for the whole creation. God’s covenant after the flood included every living creature. The prophets denounced those who destroyed the land. The Psalms celebrate creation. And in Christ, God is aligning all things, on earth and in heaven. Climate justice is therefore not only political, but deeply spiritual. To care for creation is to love our neighbour. Because when water is polluted, neighbours suffer. When harvests fail, neighbours suffer. When storms intensify, neighbours suffer. Environmental stewardship therefore, is an expression of compassion, justice, and faithfulness.

Finally, we must not lose hope. The problems are immense, yes, and it is easy to feel powerless. But the Gospel never allows despair to have the final word. Psalm 65 speaks of a God who renews the earth. Jesus reminds us that the Father knows our needs. And the resurrection of Christ proclaims that God brings life even out of death. And so, hope is not denial; Oh, no! Hope is courage rooted in God’s faithfulness. Hope is planting trees whose shade we may never sit under. Hope is teaching our children to love creation. Hope is changing habits, advocating for justice, and refusing to surrender to cynicism. Every act of stewardship becomes an act of worship. Every effort toward sustainability becomes a testimony of hope. Alone though, we cannot do much. But collectively, we can fight back. Churches can reduce waste. Families can practise stewardship. Communities can protect ecosystems. Leaders can pursue justice. And all of us can pray, teach, advocate, conserve, and live more faithfully.

Today, as we gather at the Lord’s Table, we remember that bread comes from the earth and wine from the vineyard. Holy Communion itself reminds us that God meets us through creation. As we receive these gifts, may we renew our commitment to cherish the earth from which they come. May the God who waters the earth teach us gratitude. And may future generations look back and say that in a time of crisis, the Church chose courage, stewardship, justice, and hope. And the church says?

Amen
