The resurrection was necessary for our justification because His resurrection was the basis of us being born again (1Pet. 1:3). Because His resurrection declared Him to be the victorious Risen Lord of all. Wayne Grudem explains this verse this way:
If God “raised us up with him” (Eph. 2:6), then, by virtue of our UNION WITH CHRIST, God’s declaration of approval of Christ is also his declaration of approval of us. When the Father in essence said to Christ, “All the penalty for sins has been paid and I find you not guilty but righteous in my sight,” he was thereby making the declaration that would also apply to us once we trusted in Christ for salvation. In this way Christ’s resurrection also gave final proof that he had earned our justification.
John Gill writes:
was raised again for our justification; he was raised again from the dead by his Father, to whom this is often ascribed; and by himself, by his own power, which proves him to be the mighty God; and this was done not only that he might live an immortal and glorious life in our nature, having finished the work he undertook and came about, but for "our justification". He died in the room and stead of his people, and by dying made satisfaction for their sins; he rose again as their head and representative, and was legally discharged, acquitted, and justified, and they in him. Christ's resurrection did not procure the justification of his people, that was done by his obedience and death; but was for the testification of it, that it might fully appear that sin was atoned for, and an everlasting righteousness was brought in; and for the application of it, or that Christ might live and see his righteousness imputed, and applied to all those for whom he had wrought it out.
Here I end our brief study of Christ's resurrection.
The Ascension of Christ
Luke tells us that the Lord Jesus taught His disciples about the Kingdom of God for forty days between His resurrection and ascension. With the same body, He blessed His disciples and was taken up from them.
Acts 1:8-11 But you will receive power when the Holy Spirit has come upon you, and you will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth.” 9 And when he had said these things, as they were looking on, he was lifted up, and a cloud took him out of their sight. 10 And while they were gazing into heaven as he went, behold, two men stood by them in white robes, 11 and said, “Men of Galilee, why do you stand looking into heaven? This Jesus, who was taken up from you into heaven, will come in the same way as you saw him go into heaven.”
The account is straightforward. As the Lord was speaking with His disciples, the time for Him to depart came. Therefore, He blesses them and gives them the promise of the Spirit and then is carried by a cloud into heaven. It was necessary for the Lord to depart so that the Holy Spirit would come. The Lord told His disciples –
John 16:7 Nevertheless, I tell you the truth: it is to your advantage that I go away, for if I do not go away, the Helper will not come to you. But if I go, I will send him to you.
Indeed, after ten days, on Pentecost the Spirit did come in power and glory. The ascension of Christ demonstrates that His mission was complete. He did w...
