If all who are saved have a Christlike character, then we need to find out what it is like and aim to be like Him. Salvation has never been something you can earn; it is something that those who are like Christ receive as a free gift.
Jesus bids us, “Love one another, as I have loved you. … By this shall all men know that ye are My disciples, if ye have love one to another” (John 13:34, 35). He is our mighty Helper; and if He abides in our hearts, we shall manifest His spirit. We shall love one another; we cannot help it; for He is love.
