Every follower of Christ Jesus has been given a charge. If we don't know what we have been charged with, we will come up with our own brand of Christianity that is counterfeit. We may espouse the Christian faith and love to have doctrinal discussions about the faith or talk political values but if we don't know the main goal of God's instruction to us then we become lost and drift away from Christ who loves us with a holy love.
"The aim of our charge is love that issues from a pure heart and a good conscience and a sincere faith. Certain persons, by swerving from these, have wandered away into vain discussions, desiring to be teachers of the law, without understanding either what they are saying or the things about which they make confident assertions."(1 Timothy 1:5-7)
