8 "But you, Israel, my servant, Jacob, whom I have chosen, you descendants of Abraham my friend,
7 Our God, did you not drive out the inhabitants of this land before your people Israel and give it forever to the descendants of Abraham your friend?
(Read 2 Chronicles 20:1-13)
In all dangers, public or personal, our first business should be to seek help from God. Hence the advantage of days for national fasting and prayer. From the first to the last of our seeking the Lord, we must approach him with humiliation for our sins, trusting only in his mercy and power. Jehoshaphat acknowledges the sovereign dominion of the Divine Providence. Lord, exert it on our behalf. Whom should we seek to, whom should we trust to for relief, but the God we have chosen and served. Those that use what they have for God, may comfortably hope he will secure it to them. Every true believer is a son of Abraham, a friend of God; with such the everlasting covenant is established, to such every promise belongs. We are assured of God's love, by his dwelling in human nature in the person of the Saviour. Jehoshaphat mentions the temple, as a token of God's favourable presence. He pleads the injustice of his enemies. We may well appeal to God against those that render us evil for good. Though he had a great army, he said, We have no might without thee; we rely upon thee.

Commentary on Isaiah 41:1-9
(Read Isaiah 41:1-9)
Can any heathen god raise up one in righteousness, make what use of him he pleases, and make him victorious over the nations? The Lord did so with Abraham, or rather, he would do so with Cyrus. Sinners encourage one another in the ways of sin; shall not the servants of the living God stir up one another in his service? God's people are the seed of Abraham his friend. This is certainly the highest title ever given to a mortal. It means that Abraham, by Divine grace, was made like to God, and that he was admitted to communion with Him. Happy are the servants of the Lord, whom he has called to be his friends, and to walk with him in faith and holy obedience. Let not such as have thus been favoured yield to fear; for the contest may be sharp, but the victory shall be sure.
