Mark 6:50-52 “for they all saw him and were terrified. But immediately he spoke to them and said, “Take heart; it is I. Do not be afraid.” And he got into the boat with them, and the wind ceased. And they were utterly astounded, for they did not understand about the loaves, but their hearts were hardened.”
It is hard to imagine the creator of the universe walking on the water that He created. The water was in subjection to Jesus Christ as LORD, because He was/is God! The apostles didn’t understand this yet. When Christ stopped the storm by commanding it to stop, the apostles were astounded. The bible isn’t simply a book but the inspired and infallible Word of God. It holds mystery’s to be revealed, and the primary mystery is how sinners like us could be redeemed by a holy, just, righteous and perfect God. I suggest you read the gospel of John to find out. Thank you and God bless you!
