It is a common temptation of Satan to make us give up the reading of the Word and prayer when our enjoyment is gone; as if it were of no use to read the Scriptures when we do not enjoy them, and as if it were no use to pray when we have no spirit of prayer.In other words, don't worry about your feelings. Just do it anyway.
That's something I've had to rediscover lately. It is so often clear what I should do but when I factor in if I want to do it, then I begin finding excuses. The silly thing is that giving in to those excuses doesn't make me any happier. So I might as well just go ahead and do my duty, so to speak.
