Do you think that is so? That we become obedient after we are saved?
What of Acts of the Apostles and chapter 2? Peter is in Jerusalem and speaking to thousands gathered. He and the 11 other Apostles are there.
Many in the crowd become convicted of their part in Messiahs death.
Acts of the Apostles Chapter 2
32 So Jesus is the One whom God raised from the dead. And we are all witnesses to this. 33 Jesus was ·lifted up to heaven and is now at [L exalted to] God’s right ·side [L hand; C a position of highest honor beside the king]. The Father has given the Holy Spirit to Jesus as he promised. So Jesus has poured out that Spirit, and this is what you now see and hear. 34 David was not the one who ·was lifted up [went up; ascended] to heaven, but he said:
‘The Lord said to my Lord,
“Sit by me at my right ·side [L hand;
v. 33],
35 until I ·put your enemies under your control [L make your enemies a footstool for your feet;
Ps. 110:1].”’
36 “·So [Therefore], all the ·people [L house] of Israel should know this ·truly [with certainty]: God has made Jesus—the man you ·nailed to the cross [crucified]—both Lord and ·Christ [Messiah].”
37
When the people heard this, they ·felt guilty [were deeply distressed; L were cut/pierced to the heart] and asked Peter and the other apostles, “What shall we do, ·brothers [L men, brothers]?”
38 Peter said to them, “·Change your hearts and lives [Repent] and be baptized, each 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. 39 [L For] This promise is for you, for your children, and for all who are far away [C both in space and time; may refer to Gentiles and/or Jews scattered outside the land of Israel]. It is for everyone the Lord our God calls to himself [
Joel 2:32].” "
Isn't Peter teaching there that obedience begins with doing what Jesus said to do in order to change a persons heart and life?
