And it shall come to pass that everyone who calls upon the name of the Lord shall be saved.’
Now when they heard this they were cut to the heart, and said to Peter and the rest of the apostles, “Brothers, what shall we do?” 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. For the promise is for you and for your children and for all who are far off, everyone whom the Lord our God calls to himself.” 

(‭Acts‬ ‭2‬:‭21, 37-39‬ ESV)
