"I am yours; save me, for I cherish your precepts" [Psalm 119.94 NASB]
As we continue to go on in the Christian life, we often discover that there are unwritten signs or indications, which clearly separate a genuine believer from a pretend one. David loved his wives; but at the same time, as an indication of his love for God, he cherished His precepts.
To the man without the Spirit, this unwise decision would have been a complete waste of time and energy; but to the spiritual man, it is a clear indication of the unseen God at work in his life.
Every day we are constantly involved in a spiritual battle on different levels, and we always stand in need of God's help to enable us to meet and defeat all of our enemies. We will never reach in this lifetime the platform of self-sufficiency necessary to fight our own spiritual battles.
The truth is that the longer we serve God, the more we realize that it is all of Him, and that we need to daily exchange our many weaknesses and inefficiencies for His adequate-for-anything strength.
This is what David was doing here. Once again, he had come to the end of himself, and like Paul he could cry out from the platform of complete desperation, "Our sufficiency is of God."
This total dependence upon God is an indication of spiritual maturity. [David McArdle]
