Question: Who was the very first person to enter Heaven?

Answer: Colossians 1:18 calls Jesus the “firstborn from the dead”: “And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence.” And Revelation 1:5 also tells us this: “And from Jesus Christ, who is the faithful witness, and the first begotten of the dead…”

This means that Jesus was the first being who entered heaven after his death. And this is what Apostle Peter preached in Acts 2, when he explained that Jesus was in heaven and yet King David was not yet in heaven:

Acts 2:29 “Men and brethren, let me freely speak unto you of the patriarch David, that he is both dead and buried, and his sepulchre is with us unto this day. Therefore being a prophet, and knowing that God had sworn with an oath to him, that of the fruit of his loins, according to the flesh, he would raise up Christ to sit on his throne; He seeing this before spake of the resurrection of Christ, that his soul was not left in hell [hades, the death state], neither his flesh did see corruption. This Jesus hath God raised up, whereof we all are witnesses. Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Spirit, he hath shed forth this, which ye now see and hear. For David is not ascended into the heavens: but he saith himself, The LORD said unto my Lord, Sit thou on my right hand, Until I make thy foes thy footstool.”

Peter is saying that David was still in the death state, but that Christ was resurrected, delivered from the death state after three days.

And John 3:13 confirms this: And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven.

The Heavenly Father rewarded his only-begotten son, Jesus Christ, with the divine nature at his resurrection, after Jesus faithfully laid his life down as a ransom for all. Hebrews 12:2: Looking unto Jesus the author and finisher of our faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God.
