One reason why so many Christians are not too eager to grow in their spiritual lives is because when they look around, they see lots of Christians who are far worse than they are. They see many who are more broken, more messed up and struggling.
Here lies the problem: the point of comparison is flawed. The Bible never told us to measure our lives using our neighbors’ yardstick. In 1 Corinthians 11:1, Paul urged the believers to imitate him as he imitated Christ. The point is in the imitation of Christ, not of Paul. We are to look to Christ (Hebrews 12:2) as the ultimate yardstick. Then we will see how we all don’t measure up and how we all need the grace of God.
You will never become like Christ by fixing your eyes on your churchmates. You will never grow if your mind is fixed on the immaturities of others.
