Mark 1:15 "The time is here, and the kingdom of God is at hand. Repent, and believe in the gospel."
1Cor 15:1-4 The gospel is that Jesus Christ died for our sins according to the Scriptures, that He was buried, and then He was resurrected on the third day.
Romans 4:25-5:2 He was delivered over to death for our sins and then was raised to life to put us right with God. By faith in this, then, we have peace with God through our Lord Jesus Christ, through whom we have gained access by faith into this grace in which we now stand.
Romans 10:9-11 If you confess with your mouth, "Jesus is Lord," and believe in your heart that God raised Him from the dead, you will be saved. For with your heart you believe and are put right with God, and it is with your mouth that you confess and are saved. As the Scripture says, "Anyone who trusts in Him will never be put to shame."
1 John 1:3-4 That which we have seen and heard we declare to you, that you also may have fellowship with us; and truly our fellowship is with the Father and with His Son Jesus Christ. We write these things to you that your joy may be full.
