A.B. Simpson emphasizes the importance of rejoicing in the Lord and the futility of dwelling in depression. He encourages believers to focus on the cross, where they can find cleansing and a new identity in Christ, allowing them to rise above their past faults. By laying down their burdens and embracing their standing in Jesus, they can transform painful experiences into lessons of victory. Simpson highlights that praise is a powerful sacrifice that pleases God and should be offered continually, as it brings light to even the darkest moments. Ultimately, he calls for a life of constant rejoicing, reminding us that a single moment of negativity can overshadow our joy.

There is no spiritual value in depression. One bright and thankful look at the cross is worth a thousand morbid, self-condemning reflections. The longer you look at the evil the more it defiles and mesmerizes you into its own likeness. Lay it down at the cross, accept the cleansing blood, reckon yourself dead to the thing that was wrong, then rise up and count yourself as if you were another man or woman. Identifying yourself with the Lord Jesus, you may then accept your standing in Him and look in your Father's face as blameless as Jesus. Then out of your every fault will come some lesson of watchfulness or some secret of victory that will enable you some day to thank Him, even for your e painful experiences. But praise is a sacrifice for it is acceptable to God. It ascends to heaven sweeter than the songs angels, a sweet smelling savour (Ephesians 5:2) to your Lord. It should be the sacrifice of praise to God continually (Hebrews 13:15). One drop of poison will make the whole cup a cup of death, one moment of gloom will defile a whole day of sunshine. Let us rejoice evermore (1 Thessalonians 5:16).
