Theological fitness refers to that persistent fight to exercise our faith by actively engaging in the gospel truth revealed in God's Word. Every Christian will persevere, but whatever stage of the race we may find ourselves in, we respond to our trials, triumphs, and ordinary circumstances according to what we believe to be true about God and His work. One thing is for sure: we cannot hold fast to a confession that we know little about. A good servant of Jesus Christ is trained in the Word of the faith. This takes a fighting mentality.
