With great concern and sympathy the inspired writer warns that the 'heart' (encompassing mind, affections, will and conscience) may be luring us into unbelief or rebellion against God. Here are the dangers, and the only remedy for the power of unseen inner prejudice against God.

Paul presents four tremendous graces given to believers to exercise and keep in view constantly, lifelong - the doctrine of salvation, the gift of wisdom (here explained), the practice of melody in the heart through psalms and hymns, and a strong awareness of representing Christ.

Job is denounced by his justified-by-works friends, but refutes their ideas. He criticises God for not having a complaints procedure for people like himself, yet at the same time, he witnesses to his friends in a magnificent poem on finding wisdom and truth.

Job longs for an explanation of his suffering, and for vindication before his 'friends'. As his friends denigrate him, and his gloom deepens, he is suddenly given a moment of revelation about his personal Redeemer-God, incarnate, and visible to him in a final resurrection.

Job's 'friends' increase in hostility with charges of hypocrisy. Job clings to his evangelical view of grace, and upholds God's perfection, but lapses into self-pity. He then eloquently trounces and disproves the liberal theology of the friends, and proclaims his testimony of salvation.
