Dr AR Bernard of the Christian Cultural Center in Brooklyn, Ny USA once said... being biblical does not make one Christian... A Christian is a follower of Christ.
Attending Church does not make one Christian. A Christian is one who's committed to Christ not just in word but deeds and lifestyle. One whose mind has been renewed and transformed to be more like Christ. There's a saying that goes as follows... preach the gospel always, only when necessary use words.... Our words are only as valuable to the degree that our life reflects our message.
Commit to the truth-true Christianity is synonymous to Christlikeness by pledging to be or continuing to be a true Christian, that is... living a ChristLike life. Living a life that reflects the character of Christ. Adopting the belief that true Christianity is synonymous to ChristLikeness.
