Because He drained His cup (the cup of wrath)
ours can overflow. (the cup of blessing and salvation)
He offers this with love,
with Spirit to know.
After His Resurrection, the Savior taught the Nephites: “I have drunk out of that bitter cup which the Father hath given me, and have glorified the Father in taking upon me the sins of the world, in the which I have suffered the will of the Father in all things from the beginning” (3 Nephi 11:11). In addition to the “cup of wrath,” the Old Testament contains references to a cup of blessing and salvation (see Psalms 16:5; 23:5; 116:13). In the great exchange of the Atonement, the Savior drank out of the “bitter cup” (3 Nephi 11:11; D&C 19:18) for us so that He could offer us “the cup of blessing” (1 Corinthians 10:16 The cup of blessing which we bless, is it not the communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ?). For more information about “the cup,” see the commentary for Mark 10:38–39.
