Morality by consensus. That’s the way so many of us live, avoiding the things we collectively determine are wrong while affirming the things we determine are right and good. By consequence, our morals are in constant flux, constant transition, as they respond and adapt to the spirit of the age. This is true outside of the church and, sadly, true even within Christian culture.
In The Discipline of Grace Jerry Bridges challenges us that “if we are going to make progress in the pursuit of holiness, we must aim to live according to the precepts of Scripture—not according to the culture, even the Christian culture, around us.” But we can’t do this if we don’t know what those precepts are and we can’t know what those precepts are unless we are immersed in the Word of God. Says Bridges,
To pursue holiness, one of the disciplines we must become skilled in is the development of Bible-based convictions. A conviction is a determinative belief: something you believe so strongly that it affects the way you live. Someone has observed that a belief is what you hold, but a conviction is what holds you. You may live contrary to what you believe, but you cannot live contrary to your convictions.
Thus Bridges wants us to see that there is a difference between your beliefs and your convictions. We can believe all the right things but still have very wrong convictions. He shows that when it comes to convictions, Bible presents us with something like an “influence continuum.” On one side of a line is sinful society and on the other side is the Word of God. We all exist somewhere on this continuum, influenced to lesser or greater extent by each. “Our attitude toward the Word of God and the time we spend thinking about it. Nothing else will determine where you are on that continuum.” As Christians mature, they move to the “God’s Word” side of the continuum, being influenced more by God and less by society.
