Man's Response
Repentance begins with a recognition and confession that what God says about us is true that we have sinned.
For I know my transgressions, and my sin is ever before me. Against You, You only, I have sinned and done what is evil in Your sight, so that You are justified when You speak and blameless when You judge. Psalm 51:3-4
A genuine recognition of our sinfulness and guilt will also lead to genuine sorrow, shame and even hatred for what we have done.
For what I am doing, I do not understand; for I am not practicing what I would like to do, but I am doing the very thing I hate. Romans 7:15
Wretched man that I am! Who will set me free from this body of death? Romans 7:24
Apparent sincerity of confession alone is never definite evidence of genuine repentance. It must be accompanied by a turning away from sin.
Wash yourselves, make yourselves clean; remove the evil of your deeds from My sight. Cease to do evil. Isaiah 1:16 therefore every tree that does not bear good fruit is cut down and thrown into the fire. Matthew 3:10
Faith Defined
Now faith is the assurance of things hoped for, the conviction of things not seen. Hebrews 11:1
and being fully assured that what God had promised, He was able also to perform. Romans 4:21
Faith Based on The Promises of God
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. John 3:16
Believe in the Lord Jesus, and you will be saved Acts 16:31
Example of a Believer
Worship in the Spirit of God and glory in Christ Jesus and put no confidence in the flesh Philippians 3:3
The Basis of Genuine Assurance
True conversion: A true Christian is a new creation and will live a life that reflects God's radical work of re-creation in his/her life. Therefore if anyone is in Christ, he is a new creature; the old things passed away; behold, new things have come. 2 Corinthians 5:17
You will know them by their fruits. Grapes are not gathered from thorn bushes nor figs from thistles, are they? Matthew 7:16
Assurance is based upon self-examination in the light of Scripture. Test yourselves to see if you are in the faith; examine yourselves! Or do you not recognize this about yourselves, that Jesus Christ is in you unless indeed you fail the test? 2 Corinthians 13:5
These things I have written to you who believe in the name of the Son of God, so that you may know that you have eternal life. 1 John 5:13
