Psalm 18:1-3 I will love thee, O Lord, my strength. The Lord is my rock, and my fortress, and my deliverer; my God, my strength, in whom I will trust; my buckler, and the horn of my salvation, and my high tower. I will call upon the Lord, who is worthy to be praised, so shall I be saved from mine enemies.
David sang this psalm on the day the Lord delivered him from the hand of all his enemies, and from the hand of Saul. In the midst of threat and danger, David could still love the Lord. He could trust Him because the Lord is his rock, fortress, deliverer, God, strength, buckler, horn, and tower. With that kind of God as his God, David could call upon the Lord in every trouble and know that he would be saved from all enemies.
Every day we are hard pressed by our spiritual enemies, Sin, Death, and the Devil. But every moment we have our powerful Warrior by our side fighting for us. Jesus has soundly and decisively defeated our enemies at the cross and the empty tomb. There He won the victory for us. And He sent the Holy Spirit into our hearts by faith to give us confidence and assurance. We cannot be overcome. Our God overcame and won the victory through the awesome power of sacrificial love, the greatest power in the universe.
Therefore, we call upon, praise, and trust Him. Prayer and faith is our God-given response to the pains and worries of a sin-ridden life on earth. We fear, love, and trust God because He first loved us in Christ. We call and are delivered.
