Ephesians 5:25-27, Titus 2:14, Titus 2:11-12, 2 Corinthians 7:1, Titus 1:16, Hebrews 12:14, 2 Thessalonians 2:13-14, Romans 8:13, and
Romans 8:1 (KJB).
I believe the Bible teaches that there are different ways to overcome grievous sin
(mortal sin) by God's Word and with the help of Jesus:
- Remove yourself from sinful environments (if possible) and or get rid of things that cause you to sin. In Genesis: Joseph had literally ran away from the temptation of sexual sin.
- Pray to God so as not to be tempted. It is part of the Lord’s prayer for you to pray so as not to be tempted into sin. God will guide and protect you if you are serious in praying for this. In fact, fasting will help you with this, as well.
- Obey God’s righteous ways. The more you love God and love others and obey His Word and stay in His Word and pray, the more you will not even have a chance to sin or do the wrong thing. But the more you walk in God's Word by the Spirit you will not fulfill the lusts of flesh (See: Galatians 5:16).
- When you are tempted, quote Scripture. When Jesus was tempted by the devil, He quoted Scripture to defeat the devil. So when some specific sin is bothering you, find all the verses you can that are victory verses over that particular sin. A good general verse is, “The Lord is my shepherd, I shall not want.” You can say these verses to yourself silently under your breath (with nobody hearing).
- Ask for prayer from other God fearing Christians or Godly Christians to help you to overcome certain sins. The Scriptures say, bear ye one another's burdens and thus fulfill the Law of Christ. So seek true fellowship and ask for their help.
- Hide God’s Word in your heart. Memorize Scripture. David said he hid God’s Word within his heart so that he may not sin against the Lord.
- Confess of your sins. 1 John 1:9 says if we confess our sins he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.
Faith comes by hearing and hearing the Word of God (Romans 10:17).
The faith is hearing all of the Bible and not just the parts we want to hear.
In other words, to answer your question:
It would be applying proper faith
(the other side of the coin of faith, i.e. the “work of faith”) so as to continue to access the saving grace of God.
Important Note: The first side of the coin of faith is in receiving Jesus Christ as our Savior (John 1:12), and in trusting in the gospel in 1 Corinthians 15:1-4, and in seeking forgiveness with Him (Romans 10:13).
Anyways, make no mistake that the other side of the coin of faith is the work of faith.
How so?
Well, first, Paul talks about how there is the “
work of faith” in 1 Thessalonians 1:3, and 2 Thessalonians 1:11. Second, we learn in 1 John 1:7 that if we walk in the light
(abide in the light of God - 1 John 1:6, and love our brother - 1 John 2:9-12) the blood of Jesus Christ cleanses us from all sin. For faith without works is dead (James 2:17) (Also see James 1:12, and James 1:21).
John the baptist said,
“Bring forth therefore fruits worthy of repentance,...” (Luke 3:8).
“...the axe is laid unto the root of the trees: every tree therefore which bringeth not forth good fruit is hewn down, and cast into the fire.” (Luke 3:9).
Jesus said:
“And cast ye the unprofitable servant into outer darkness: there shall be weeping and gnashing of teeth.” (Matthew 25:30).
The apostle Paul said that one of the marks of deceivers is that we can deny God by a lack of works. For it is written:
“...there are many unruly and vain talkers and deceivers, (Titus 1:10) ....
“They profess that they know God; but in works they deny him, being abominable, and disobedient, and unto every good work reprobate.” (Titus 1:16).
Jesus said:
“And shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation.” (John 5:29).
Peter said,
“But there were false prophets also among the people, even as there shall be false teachers among you,” (2 Peter 2:1) ... “Having eyes full of adultery, and that cannot cease from sin; beguiling unstable souls: an heart they have exercised with covetous practices; cursed children: Which have forsaken the right way, and are gone astray,...” (2 Peter 2:14-15).
Jude 1:4 (NIV) says,
“For certain individuals whose condemnation was written about long ago have secretly slipped in among you. They are ungodly people, who pervert the grace of our God into a license for immorality and deny Jesus Christ our only Sovereign and Lord.”
Note:
In regards to Jude 1:4 saying that a these individuals denied Jesus Christ: Again, a person can deny God by a lack of works (See again: Titus 1:16).
