The gospel is essential for Christians to cherish in their lives. It is not something that served a purpose when you met the Lord and now no longer matters. If that is the case you will become either legalistic (an improper fixation on law or codes of conduct for a person to merit) or antinomian (Christians are under no obligation to obey the law). As Tim Keller says, “the gospel is not the ABC’s of the Christian faith but the A to Z”. It’s not just something that’s needed at the ‘beginning’ and then move onto something else. We grow by reapplying and re-grasping the reality of the gospel in every area in our lives.
“There is nothing in us or done by us, at any stage of our earthly development, because of which we are acceptable to God. We must always be accepted for Christ’s sake, or we cannot ever be accepted at all. This is not true of us only when we believe. It is just as true after we have believed. It will continue to be true as long as we live. Our need of Christ does not cease with our believing; nor does the nature of our relation to Him or to God through Him ever alter, no matter what our attainments in Christian graces or our achievements in behavior may be. It is always on His “blood and righteousness” alone that we can rest.” -BB. Warfield, Perfectionism, Part One, vol. 7 of The Works of Benjamin B. Warfield, pg 113
Let me illustrate it this way. I’m not a patient person by nature. I struggle with impatience. However, this has been something I’ve actually been growing in. Years ago, I would go through cycles of being “more” or “less” patient. And even when I was more patient I would just act out or struggle in another area. The problem was I just said “I need to be more patient I’m a Christian leader.” Well, guess what? It never lasted and I didn’t really change. It wasn’t until I lived in and moved out of the new life I have in Christ that I grew in areas like this.
