Through personal faith in Jesus Christ any person can accept God’s offer of reconciliation. This faith expresses itself through regret for one’s own sins and the wish to begin a new life with Jesus Christ.
Yet to all who did receive him, to those who believed in his name, he gave the right to become children of God.
So in Christ Jesus you are all children of God through faith.
1 Peter 1,8-9
Though you have not seen him, you love him; and even though you do not see him now, you believe in him and are filled with an inexpressible and glorious joy, for you are receiving the end result of your faith, the salvation of your souls.
When the people heard this, they were cut to the heart and said to Peter and the other apostles, “Brothers, what shall we do?” Peter replied, “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.
Repent, then, and turn to God, so that your sins may be wiped out, that times of refreshing may come from the Lord,
Make every effort to live in peace with everyone and to be holy; without holiness no one will see the Lord.
