John 17:21 “That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me.”
Unity among believers is the living witness that God sent the Lord Jesus into the world as Savior. When the world looks at Christians they will either say, surely God did send Jesus into the world because this person’s life reflects that truth; or they will say if that is what a Christian is, I don’t want to be one.
Let me encourage you to look at one area of your life today and ask God to reflect Christ through you for others to see.
Others, others, others would I see,
Let me live for others, till I burn out for Thee.
