We speak of “hitting a wall”, meaning we go as far as we can or take something as far as we can, unable to make any more progress.
We experience this in many ways. As followers of Christ our calling is to be like Him. To be like Him in character, loving, kind, patient, joyful, etc….and often the reality is we are loving, kind, patient, joyful etc..to a point and then we hit a wall. Our love, kindness, patience run out and we start to be something else.
David says in his song in 2 Samuel 22 ( which is virtually identical to Psalm 18 ), verse 30 “By my God I can leap over a wall”. He testified that with God’s help he could do things that he couldn’t do alone. When he “hit a wall” he got passed it, over it with God’s help.
It’s only with God’s help that we’ll move beyond our walls, “leap over” them, push beyond the limits of our current capacity and ability. It’s only with God’s help we’ll leap over the wall of our own selfishness, irritability and impatience that currently limit our capacity in relationships.
Paul expressed David’s sentiment in Philippians when he said ” I can do all things through Christ who strengthens me” ( Philippians 4:13). Paul was saying when I “hit a wall”, reach the end of my limits, I can go further and do more through Christ.
It is only with God’s help through Christ that we can move ahead when we “hit a wall”.
