This is a KJV Bible study guide. Please see Romans 3:25 and Proverbs 28:13, Romans 3:26 [we must believe] and 2 Peter 1:9 also. Notice in Romans 3:25 that your repentance removes your sins that are past, only. This does not cover sins that you have not committed yet, but may in the future. See the definition of propitiation below. “Past” is word # G4266 in a Strong's Concordance; read the definition for yourself.
The "forbearance of God", is the patience and long-suffering that God has for each soul, as He waits for each of us to repent, and come to Him. He withholds His wrath from us, patiently waiting on each of us to repent. Remember in 2 Peter 3:9, Our Heavenly Father is very patient. See Matthew 18:14 also [God doesn't want your soul to perish].
What is still in the world once you are forgiven? Your flesh body and worldly temptations are still there. Can you deny that? I don't think so. If you fall short in the future, do you honestly believe God gives you a pass? What you would be trying to tell God is, just look the other way when I sin in the future; and, you will sin more than likely, you are just a human. Plus, who are you to tell God what to do? Who would want you to think you can sin in the future and get away with it? Who beguiled Eve in the Garden of Eden? Read 2 Corinthians 11:3 for the answer. Repent and get back on track. No need to be baptized and saved again, in effect re-crucifying Christ. You messed up, not Jesus. Please read Jeremiah 3:13. Turn from [repent of] your sin and be saved [God already knows what you have done, you can't hide it from Him]. Do the opposite and you will not be saved. Separate yourself from the sin, don't separate yourself from God with sin that hasn’t been repented of on the books. Plain and simple.
See 1 John 1:6-10; verse 10 is very important. Also, see Galatians 2:17. What do we do when we stumble, and fall into the mud of sin? Like children learning to walk, we get up (repent) and clean ourselves off through God's forgiveness, then get back up again, and resume walking. Our heavenly Father's will is for us to walk with Him, have fellowship with Him, and receive of His abundant blessings. He desires that we be open and honest before Him, and to be cleansed of our sins, so that we will be able to walk with Him in His path each day. Our sins separate us from God, see Isaiah 59:2. Do you want to remain separated from God?
*Are you cleansed of sin if you are actively involved in committing a sin? No!!!
*How can God still declare us righteous if we sin in the future? Something to meditate and study on.
Ezekiel 33:12, 13, 18, 19; repent and live. [Also, see 2 Samuel 24:10; As soon as David realized he had sinned, he repented. A really good example for us! See 1 John 1:8-10 again. Ezekiel 18:21-28, 30-31; repent of past sin (hath committed, not will commit in the future) and live. Also, see Luke 9:62 (don't go back to sinful ways, remember, sin separates you from God).
1. The act of appeasing wrath and conciliating the favor of the one offended, [God]; the act of making propitious. [See Romans 3:25 above.] In theology, the atonement or atoning sacrifice offered to God to assuage his wrath and render him propitious to sinners. Christ is the propitiation for the sins of men. Question: What does non-belief in the propitiation result in?
Conciliate: stop (someone) from being angry or discontented; placate; pacify.
Turneth: Third-person singular simple present indicative form of turn [change your ways, repent].
Turn: To change; to transform; as, to turn evil to good; to turn goods into money.
When someone says future sins are already forgiven, they do err; this one future sin will not be forgiven. The sin that is not to be forgiven in the future is blasphemy of the Holy Spirit, Matthew 12:31 and Mark 3:29; it can only happen in the future when the antichrist is here on earth [the great tribulation]. See Matthew 24, Mark 13, Luke 12 and 21 for a more in depth explanation of blasphemy of the Holy Spirit.
Acts 8:22 Repent therefore of this thy wickedness, and pray God, if perhaps the thought of thine heart may be forgiven thee. (Peter is telling this person to repent now for what they just did; Peter did not say that this sin was already forgiven. Read Acts 8:18-22 to get the whole picture).
Repentance is an ongoing, continuous attitude of wanting to change, of wanting to do better; to grow, overcome and become more like Christ on a daily basis (See Matthew 21:28-32, this is a good example; after a sin is committed, we must repent), (we are commanded to repent, Acts 17:30). It is not a one time act [one and done] as many have been led to believe by false teachers; it takes time. You have to continually work at it. Repentance includes true sorrow for sin and a turning away from it. We shall not renounce sin unless we see it for what it is, and what it results in; it separates us from God [see Isaiah 59:2 again, plus, see Psalm 5:4, Isaiah 13:11 and Jeremiah 5:25]. Until we turn away from it in our hearts, there will be no real change in our lives, the kind of change we truly need. I'm very sad to say, some will never turn from it. It can't be more plain. Study the Bible yourself as often and as much as possible. You will be amazed at what is actually in God's word that you will never hear while sitting in a church pew.

Remember, repentance has to be done in truth. You cannot con our Creator.
