Matthew 14:28-31 And Peter answered Him and said, Lord, if it is you, command me to come to You on the water. And He said, "Come." And when Peter got out of the boat, he walked on the water, to go to Yeshua (Jesus). But when he saw that the wind was boisterous, he was afraid; and beginning to sink, he cried out, saying, "Lord, save me!" And immediately Yeshua (Jesus) stretched out His hand, and caught him, and said to him, "You of little faith, why did you doubt?"
When Peter stepped out of the boat to walk on water – he literally stepped out of the boat! Imagine that! But was Peter going overboard? No, I don't believe so -- he was literally taking a step of faith with his eyes fixed on the Lord!
Often, when we step out in faith – it may appear that we are going overboard, but are we really? Honestly, the question is -- "Can you really go overboard in your faith toward God?" I don't think so! When our passion is no longer on the Lord, then that's when we're going overboard.
When you love the Lord God with "all your heart, mind and soul"-- it's okay to step out and go all out for God -- because in God, the only way to go overboard is to not go overboard enough!
