The Gospel
While maintaining His holiness and justice, the Bible also affirms that God is love, and that in love He has responded to the plight of man.
For all have sinned and fall short of the glory of God, being justified as a gift by His grace through the redemption which is in Christ Jesus; whom God displayed publicly as a propitiation in His blood through faith. This was to demonstrate His righteousness, because in the forbearance of God He passed over the sins previously committed; for the demonstration, I say, of His righteousness at the present time, so that He would be just and the justifier of the one who has faith in Jesus. Romans 3:23-26
God is love. By this the love of God is manifested in us, that God sent His only begotten Son into the world so that we might live through Him. In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins. 1 John 4:8-10
Repentance begins with a recognition and confession that what God says about us is true that we have sinned.
A genuine recognition of our sinfulness and guilt will also lead to genuine sorrow, shame and even hatred for what we have done.
Apparent sincerity of confession alone is never definite evidence of genuine repentance. It must be accompanied by a turning away from sin.
