Acts 2:38, in fullfillment of John 3:3-5, tells everyone how to obey the Gospel.
Time is running out. The night comes when no man can work.
Why tarry ye?
Arise and be baptized and wash away thy sins calling on the Name of the LORD, TODAY, the Day of Salvation.
Repent that you might believe the Gospel of repentance and remission of sins to the Jew first and also to the Gentile, the everlasting Gospel of the Kingdom that shall be preached in all the world for a witness unto all nations; and then shall The End come.
Please don't stop there but prayerfully, studiously, verify the clear pattern of this key verse of salvation -Acts 2:38, in the following verses for yourself:
John 3:3-5 Acts 1:4; 2:4; 2:36-40; 8:12-20; 9:1-20 10:42-48; 16:27-33; 19:1-7 and 22:16 There is but one and no other gospel is to be preached as witnessed in I Peter 4:17, II Thessalonians 1:8-9 and Galatians 1:8-9 In the mouth of two or three witnesses is every word established.
We do not find a single conversion account in the Book of Romans but a compilation of conversions can be found in the Book of Acts.
Acts is where the ACTion is. The Book of Acts is where people first obeyed the Gospel. Acts is where people ACTually get saved!
