I wonder how many Christians lead joyless lives because they wallow in the weight of their past sins. “If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness” (1 John 1:9). Repent, confess, ask for forgiveness (early and often), and pray for joy. Therefore, we are to consider the trials of this life pure joy, more than happiness, for God is at work in us for our good and his glory.
In an age which has a low view of the church, this may sound startling. Yet, it is to the church that Christ has given his commission, commands, and keys. It is in and through the church that God matures, his children with his promises and presence.
All that we need to know, all that we need to mature, all that we need for “every good work” is given to us in the Word.
