By Pastor Dr. Ronnie W. Wolfe
David is not asking for God to save him in this quickening, but he is begging for life more abundant in his service for the Lord, strength to serve, comfort in time of trouble, peace in time of confusion, love in time of tempting hate, acceptance of life's trials and concerns, and his interest in God and his word and work.
It is God's lovingkindness that keeps the believer quickened, lively, to do his work. It is the tenderness, longsuffering, mercy, and grace that sustains us in this short, unsure, and catastrophic life. We do need to be quickened, as we often backslide, sin against our God, and forget his many benefits. Only he can revive us again!
This quickening of God through his Son and the Holy Spirit is the only way that we can keep, be faithful to, and guard the testimony of God's mouth, the Bible; so we so desperately need this quickening in our lives each day that we live and serve our God.
1 John 5:9 If we receive the witness of men, the witness of God is greater: for this is the witness of God which he hath testified of his Son.
