In our walk with God we ought to walk circumspectly & circumspectly means accurate, all God wants is that you will walk accurate with him by putting former things behind us & focusing on him.
In this scripture Jacob was alone & he began to wrestle with God until the break of day & Jacob had saw that he did not prevail against God, then God touched the socket of Jacob's hip then it moved out of joint. When God touched the socket of Jacob's hip & it moved out of joint, God was trying to show Jacob that his walk wasn't accurate with him, so God had to dislocate Jacobs hip & your hip is responsible for your walk, so God dislocated Jacob's hips, in the natural to show him in the spiritual that he was not walking accurately with God. When God causes us to change our walk with him, it will be very painful that's why its so important that we walk accurately ourselves rather then letting God to dislocate our hips & make us walk accurately. When we walk accurately there is a identity change from Jacob that means deceiver to the name Israel that means the one that rules & reigns as God on the Earth.
Its very fearful to be under the hand of the living God that he could just take away our breathe within a split second but because he loves us his mercies are renewed every morning & to whom much is given, much is required so there need to be accurate walking.
