3 You whom I love, I ◄was very eager/very much wanted► to write to you about that which we all ◄share/have in common►, which is how ◄God/Jesus Christ► has saved us. But now I realize that it is necessary for me to write to you in order to exhort you to defend the truth about Christ that we believe. Jesus and his apostles gave that truth once and for all to us who belong to God, and we must not let it be changed {anyone revise/change it}.
