Hopefully making theology simpler to understand! (2 Corinthians 1:12)

And Peter said to them, “Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit.

Acts 2:38, ESV

When we repent and believe in Christ, we receive the Holy Spirit, and He helps us glorify Christ by loving others and sharing the good news of Christ.
