About the power of faith in life:

To stop worry --

Who of you by worrying can add a single hour to his life? � "And why do you worry about clothes? See how the lilies of the field grow. They do not labor or spin. � Yet I tell you that not even Solomon in all his splendor was dressed like one of these. � If that is how God clothes the grass of the field, which is here today and tomorrow is thrown into the fire, will he not much more clothe you, O you of little faith? � So do not worry, saying, 'What shall we eat?' or 'What shall we drink?' or 'What shall we wear?' � 

To feast in heaven --

For I myself am a man under authority, with soldiers under me. I tell this one, 'Go,' and he goes; and that one, 'Come,' and he comes. I say to my servant, 'Do this,' and he does it." � When Jesus heard this, he was astonished and said to those following him, "I tell you the truth, I have not found anyone in Israel with such great faith. � I say to you that many will come from the east and the west, and will take their places at the feast with Abraham, Isaac and Jacob in the kingdom of heaven. � 

To heal ---

Some men brought to him a paralytic, lying on a mat. When Jesus saw their faith, he said to the paralytic, "Take heart, son; your sins are forgiven." � She said to herself, "If I only touch his cloak, I will be healed." � Jesus turned and saw her. "Take heart, daughter," he said, "your faith has healed you." And the woman was healed from that moment. � You killed the author of life, but God raised him from the dead. We are witnesses of this. � By faith in the name of Jesus, this man whom you see and know was made strong. It is Jesus' name and the faith that comes through him that has given this complete healing to him, as you can all see. �
