Jesus has just fed the five thousand with five loaves and two fish when …
Immediately he made his disciples get into the boat and go before him to the other side, to Bethsaida, while he dismissed the crowd. And after he had taken leave of them, he went up on the mountain to pray.
And when evening came, the boat was out on the sea, and he was alone on the land. And he saw that they were making headway painfully, for the wind was against them. And about the fourth watch of the night he came to them, walking on the sea. He meant to pass by them, but when they saw him walking on the sea they thought it was a ghost, and cried out, 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. Mark 6:45-52 (ESV – emphasis by author)
Jesus’ disciples, His most intimate relationships and those closest to him, did not understand. In this they are like us. They knew Jesus better than anyone else. They were his companions. They witnessed the revelation and power of his teaching first hand. They saw him heal and give life back to the dead, turn water to wine, and calm the sea with His presence. Yet they did not understand, and because they did not understand their hearts were hardened. They were just like us. Many of us think we know, we think we believe, but we believe only so much as we understand. Without knowing and understanding we do not believe.
One cannot believe in part and not believe in part. We either do or we do not. Double mindedness, double heart-edness, is a path to confusion, rationalization, and sin. Sin that we justify because we do not understand, because we do not believe in full, because we do not abandon ourselves completely to our Lord. We place our minds over our hearts and our soul over our spirit, thus making our faith subservient to this fallen world. We are created as spirit beings, but unbelief constrains our lives. When we give our heart we must give it all, without reservation.
We are spirit beings that live in a body that has a soul. When we restore the natural order of spirit first then we open the gates to what God intended for us. With spirit, body, soul, and heart aligned as God intended, our soul rests in its intended place of peace. No longer straining to control and drive us, it is free to help us experience the fullness that our Creator designed for us.
We must believe fully to experience fully. Let go of the reins of control, tell your body and soul to take a back seat, and let your spirit do the driving.
