Matthew 1:21 And she shall bring forth a son, and thou shalt call his name JESUS, for he shall save his people from their sins.
This unconditional Christmas Promise is a bedrock of the Gospel Message. The angel give Joseph a command and a promise. “Call Mary’s son Jesus ,” for the name carries a rich and profound meaning: it means “the Salvation of the Lord,” or “Yahweh Saves.” Jesus saves! That is the promise given in the name of the Son of God who became the Son of Man. That promise has been fulfilled in the person, life, death, and resurrection of Jesus Christ.
Jesus will save His people. His own people historically, culturally, genealogically, geographically, politically, and religiously are the Jews, the children of Israel, the sons of Abraham. They are the sons of the Promise given to Judah, Jacob, and Abraham. But in the NT all peoples, Gentiles included, who hold the same faith in the promised Savior, Jesus, have become “His people.” We are His saved people. One cannot read the Bible History without a convicted “Amen” that both those people and me need saving from sins.
Jesus will save us from our sins. Sin is the problem. Jesus is the solution. Jesus fulfilled the promise to save us from the Penalty of our sins, past and future, which is eternal death and separation from God. He saves us from the Power of canceled sin in the present, that is, we cannot be successfully accused of guilt and judgment, and we have the Word and Spirit to overcome temptations to sin more often, and when we do sin we are forgiven. He will save us from the Presence of Sin forever in heaven, where we shall enjoy God forever in perfect bliss.
