In giving 3 points of advice to pastors, Iain Murray gave the third as “make faith in God’s promises the daily duty.” We have as our example of this, father Abraham. In Romans 4.18-21 we read:
18 In hope he believed against hope, that he should become the father of many nations, as he had been told, “So shall your offspring be.”19 He did not weaken in faith when he considered his own body, which was as good as dead (since he was about a hundred years old), or when he considered the barrenness of Sarah’s womb. 20 No distrust made him waver concerning the promise of God, but he grew strong in his faith as he gave glory to God, 21 fully convinced that God was able to do what he had promised.
Abraham’s circumstances didn’t seem to communicate that God was going to keep his promise. Surely the temptation to doubt and despair was there. But Abraham did not consider the inability of himself or Sarah to bar the ability of God. Rather he grew strong in faith, giving God glory, and believed that God would do what he promised.
The situations we find ourselves in are varied and distinct from Abraham’s and from each other, but our response to them all ought to be the same – faith/belief in the promises of God. All of these promises find their grounding in Christ in the gospel. Each day we must start with faith in the gospel of Jesus Christ as the answer for our sin and infirmity. What a joy for a Christian to have as his or her Father the God who is able.
