Job 22:21-23 Acquaint now thyself with him, and be at peace: thereby good shall come unto thee. Receive, I pray thee, the law from his mouth, and lay up his words in thine heart. If thou return to the Almighty, thou shalt be built up, thou shalt put away iniquity far from thy tabernacle.
Eliphaz believed that suffering is God’s punishment for evil deeds, so he suggested several sins that Job might have committed. He wanted to restore Job, but first confession and repentance would be necessary. Conventional wisdom said that suffering is a punishment for some sin and physical blessing comes from being good. But Job contended that he was innocent.
This common belief is wrong thinking, of course, but it is the argument underlying the Book of Job. Nevertheless, Eliphaz is speaking a truth here, something that is good for all of us, in good times and in bad: acquaint yourself with God by renewing and strengthening your faith in Christ; receive the law with repentant faith; lay up his words of Law and Gospel in your heart by hearing and believing; return to God, compelled by His love.
The result will be peace and good and being built up. Hearing the Word produces faith which receives forgiveness, life, love, peace, and joy.
