There are times in our lives when we have set our eyes on a prize and is determined to get it no matter what. Then we find ourselves constantly pushing and fighting to make it happen. Psalm 127:1 says, “Unless the LORD builds the house, those who build it labour in vain. Unless the LORD watches over the city, the watchman stays awake in vain.”
God may remove someone from our lives and we keep chasing him/her; He may close a door and we keep banging on it or using life support systems to hold on to a position. However, we need to allow God to close any door He sees fit and open the door He knows is best. God also lead us through closed doors.
If you keep trying to push water uphill as soon as you stop, it runs back down.
