All in Christ are made alive, since Christ is the resurrection and the life, death could not hold Him. He is therefore now alive forevermore, and so are you if you are in Christ. What you sow won't live unless it dies. His death means we live because Christ came back from the dead, and we are in Christ and so then we also live as He lives.
It was necessary because of sin that someone has to die. That is God's law. So Christ became sin for us and therefore he had to die. God said without the shedding of blood there is no forgiveness.
We also died with Christ, and so we were then raised with Christ
Romans 6:8
Now if we
died with Christ, we believe that we shall also live
with Him,
Colossians 2:20
Therefore, if you
died with Christ from the basic principles of the world, why, as
though living in the world, do you subject yourselves to regulations—
Colossians 3:3
For you
died, and your life is hidden
with Christ in God.
1 Corinthians 15:22
For as in Adam all die, even so in Christ all shall be
made alive.
1 Corinthians 15:36
Foolish one, what you sow is not
made alive unless it dies.
Ephesians 2:1
[
By Grace Through Faith ] And you
He made alive, who were dead in trespasses and sins,
Ephesians 2:5
even when we were dead in trespasses,
made us
alive together with Christ (by grace you have been saved),
Colossians 2:13
And you, being dead in your trespasses and the uncircumcision of your flesh, He has
made alive together with Him, having forgiven you all trespasses,
1 Peter 3:18
[
Christ’s Suffering and Ours ] For Christ also suffered once for sins, the just for the unjust, that He might bring us to God, being put to death in the flesh but
made alive by the Spirit,
Acts 2:23-25 New King James Version (NKJV)
23 Him, being delivered by the determined purpose and foreknowledge of God, you have taken by lawless hands, have crucified, and put to death;
24 whom God raised up, having loosed the pains of death, because it was not possible that He should be held by it.
25 For David says concerning Him:
‘I foresaw the Lord always before my face,
For He is at my right hand, that I may not be shaken.
