Do you believe in Jesus? That He is the Son of God? Who died on the cross for our sins, and 3 days later was resurrected from death?
That’s what that scripture in Acts talks about... believing in Christ Jesus, it’s not “works” that’ll save you but it’s the grace and mercy of God
Yes, repentance is definitely important but you must remember to know that once you ask God for forgiveness with all your heart, that you believe that you are forgiven.
I like the fact that you get prompted to pray for others
that’s a sign of compassion and maybe Gods put that compassion in your heart to pray for those people - by obeying God, it’s one of many ways of serving God, as mentioned in the first scripture.
Good on you bro
