How About Some Commitment Here?

Some Christians in their witness consistently invite unbelievers to "make a commitment to Christ." Other Christians seem to mainly invite people to "believe in Christ." Which approach is correct?

It is important to say here that both faith and commitment are part of what it means to become a disciple of Jesus Christ. Without faith in Christ, you cannot be His disciple. Without a commitment to Christ, you likewise cannot be His disciple. Both are essential. Both faith and commitment go into what it means to have a relationship with Jesus Christ.
