This is a popular saying, but it's only half the truth.
See for yourself:
“Lord, if it’s you,” Peter replied, “tell me to come to you on the water.”
“Come,” he said.
Then Peter got down out of the boat, walked on the water and came toward Jesus. But when he saw the wind, he was afraid and, beginning to sink, cried out, “Lord, save me!”
Immediately Jesus reached out his hand and caught him. “You of little faith,” he said, “why did you doubt?”
Peter got out of the boat, and started to walk on water, but he failed. He had good intentions but no follow-through.
He switched his focus from Christ to his circumstances, and Jesus said he had "little faith" or "doubt."
I confess that's often my problem too. Isn't it nice that even when we momentarily fall into doubt, we can reach up for Christ's hand?
