Hi Youths,
Some of us came into a relationship with Jesus with the expectation that all of our problems and issues, like anxiety, would go away instantly. In reality, while Jesus can and will free you from the grip of anxiety as you grow in your relationship with Him, our sin-effected bodies will continue to find ways to hold us back and cause problems for us on earth.
While there may still be problems and issues in our lives now, the good news is that as Christians, we know that the pain and problems we face now are preparing us for an eternal weight of glory beyond all comparison. Therefore, we can surrender our anxiety to God and put our faith in our Lord Jesus who has overcome death.
