Jesus addresses worry in the Sermon on the Mount not as a normal part of life, but as a serious issue that reveals our struggle to trust God completely. Through examples of birds and flowers, Jesus demonstrates that our heavenly Father provides for all His creation, making worry both unhelpful and a sign of distrust in God's goodness. Rather than being consumed by worry about material needs, Jesus calls us to "seek first his kingdom and his righteousness," promising that God will provide what we need when we focus on His purposes for our lives.
