Because of the weakness of the flesh and because of the hostility of the devil and his success in temptation, every believer has times of spiritual low. Not to justify these things or to make them sound inevitable, but through our fault and our weakness it is the case.
Perhaps I have turned aside to foolish distractions. Perhaps it is that television again, taking too much time and eroding away all my vigour. Perhaps it is un-confessed sin. There is something there and you will not break with it and bring it before the Lord. We are in a battle to some extent with ourselves, to watch the old nature and to resist rising desires. We are in a war against Satan's suggestions that come from outside, sometimes questioning our sincerity and our salvation. We have a task to carry out to spread the name of Christ. We have to engage in intercession for souls the people who God has laid upon our hearts. We have to be watchful, and we have to have self-control, and we have to learn of God and worship him.
