Many do not accept the Bible as God's infallible truth. Bible, the written truth. Grace be with you, mercy, and peace, from God the Father, and from the Lord Jesus Christ, the Son of the Father, in truth and love. God's unmerited favor. Some never find either one.
Love is an action word and is useless unless expressed.
Means nothing otherwise. Just a word. John was moved in his heart as he wrote. Love is a vary powerful force. Love moved the Son to save the sinner.
