Jesus Christ is our Mediator (I Timothy 2:5), the connection, the bridge, between God and us. Spiritual enablement flows from God through Him to us. God's power and God's faithfulness are the issues that are of supreme importance to us in these critical times. Are we constantly cognizant of the fact that our salvation lies in His hands? He has the power to save.
Notice how David expressed this in a psalm written during a time of serious trouble for him: "For look, they lie in wait for my life; the mighty gather against me, not for my transgression nor for my sin, O LORD" (Psalm 59:3). David feared the threat of murder in a situation in which he was innocent. Verses 9-10 carry his thoughts further: "I will wait for You, O You his Strength; for God is my defense. My God of mercy shall come to meet me; God shall let me see my desire on my enemies." Here, David's confidence rises because he believes in God's awareness and strength - which is strong enough to put down nations, let alone a small band of enemies. He also recalls God's mercy toward those who serve Him.
Verses 16-17 show that his thoughts extend one step further: "But I will sing of Your power; yes, I will sing aloud of Your mercy in the morning; for You have been my defense and refuge in the day of my trouble. To You, O my Strength, I will sing praises; for God is my defense, the God of my mercy." These final two verses summarize why he trusts God, and conclude in a strong affirmation of David's faith. He trusts God because of the combination of God's strengths, His power, combined with His mercy and His will to use them in behalf of those who trust Him.
