"And Peter answered him and said, Lord, if it be thou, bid me come unto thee on the water. And he said, Come. And when Peter was come down out of the ship, he walked on the water." (Matthew 14:28-29)
It's easy to be so afraid of making a mistake that you never get around to stepping out on faith. You can spend all your time wondering, "Is this faith? Or is it presumption? What if I exercise my faith for something and find out later I've missed God's will?"
Don't worry. God can handle any mistake you can make. I know because I've made plenty of them. When I did, I'd just go to the Lord and He'd tell me, "Stay on the Word, son. Together we'll overcome this thing." And we always did.
If you act on the Word out of the sincerity of your heart and you steadfastly stay with the Word, Jesus will never let you down...no matter how many dumb mistakes you make. He proved that the night Peter jumped out of the boat in the middle of the lake.
Have you ever stopped to think about that incident? Peter hadn't been praying or seeking God's will before he did that. On impulse he just blurted out, "Lord, if it's You bid me come."
What was Jesus supposed to say? He couldn't very well say, "It's not Me." I suppose He could have said, "Wait a minute now. You don't have the faith to get out here. You'd better stay in that boat or you're going to drown for sure."
But He didn't say that to Peter--and He won't say it to you. If you want to get out and walk by faith, He'll get out there with you and pick you up when you start sinking. He'll walk you back to the boat if He has to.
It's better to risk being presumptuous than to waste your life in the boat of unbelief! If you have to, just dive into the water and say, "God, help me!"
Don't let fear keep you from taking that step of faith. Come on, get out of the boat today.
