Paul's Gospel

Righteousness- equity, justice, fairness, moral correct, right doing, good, worthy, virtue, decency, honest, innocent, holy, the perfectness and pureness of Jesus Christ.

Faith-ability to believe in Christ's death, as the ground of justification before God, saving faith.

Redemption- to let go free for a ransom. Sin is presented as slavery and sinners as slaves. Deliverance from sin is freedom.

Justification- acquittal for Christ’s sake, to be justified/ excused of sin because of Jesus Christ’s death on the cross.

The “Romans road” can be used to explain the Gospel. It is similar to how Paul explains the Gospel in the first 5 chapters of Romans. Let’s take a look at these verses and also so verses beyond the first 5 chapters in Romans. First Paul starts with the problem of the sin nature.” Rom 3:10 as it is written, "THERE IS NONE RIGHTEOUS, NOT EVEN ONE.” Humans are trapped in a hopeless predicament because of sin nature. By the sin nature, men are not righteous. Rom 3:23 says “for all have sinned and fall short of the glory of God.”
Paul’s solution to the sin nature in the Gospel message is faith in Jesus Christ. Rom 10:9, 10 says “that if you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you will be saved; for with the heart a person believes, resulting in righteousness, and with the mouth he confesses, resulting in salvation.” This is faith, saving faith. We believe that as Jesus Christ was raised from the dead so we were raised with Jesus.
Jesus’ death and resurrection according to Paul’s Gospel is justification for our sin and sin nature. Christ in his righteousness (perfection) sacrificed for fallen man. Through Christ we are justified. As Rom 6:23 says “For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.” Because of our sin we are doomed to die. But through Christ we live. The only way this is possible is through redemption. Jesus justified us, acquitted us because he redeemed us through His death and blood on the cross. As Rom 5:8 says “But God demonstrates His own love toward us, in that while we were yet sinners, Christ died for us.” God allowed all of this to happen. John 3:16, “For God so loved the world, that He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life.”
