Just as paul said in Ephesians 3:1-2
For this reason I, Paul, a prisoner of Christ Jesus on behalf of you Gentiles— 2 assuming that you have heard of the stewardship of God's grace that was given to me for you
And verse 7 says:
7 Of this gospel I was made a minister according to the gift of God's grace, which was given me by the working of his power.
Indeed it's by God's grace that we are able to recieve the gospel and enjoy the gift of the holy spirit. 👍
