Partial forgiveness is therefore not good news. Especially since Jesus isn’t going to die again. What is going to be your sacrifice for your post salvation sins if Jesus isn’t going to die again? A couple of lambs? Maybe a goat? Your works? Your ability to remember, confess, cry and wail about it? Or does God go into panic mode, quickly turns back time every time somebody confesses, adds that sin in and then lets Jesus die all over again, and then fast-forwards time back to the present so we can all go on again? I highly doubt it. Jesus died 2000 years ago. Your forgiveness was fully provided at the same time. You were forgiven at the cross, not at the point of salvation. At the point of salvation you merely realized you have been forgiven already and then through faith you received His free gift of righteousness which gave you right standing before the Father.
I was encouraged to read an article by someone who "gets" the gospel. They make a very good point. If you were forgiven for only the sins you committed before your conversion then what is the remedy for sins that you are committing now? The answer is "there is no remedy" except the sacrifice of Christ on the cross. The folly of the "Lordship salvationist/works plus grace" crowd is they actually think that you can reach a point where you are living a holy enough life that you don't need a Savior. The truth of the matter is that Christ forgives us "unconditionally" for all the sins we will ever commit. That's right, I said it...all! There is no arguing this fact, that is, if you believe the Bible.
Hbr 10:12-18 But this Man, after He had offered ONE sacrifice for sins FOREVER, sat down at the right hand of God, 13 from that time waiting till His enemies are made His footstool. 14 For by ONE OFFERING He has perfected FOREVER those who are being sanctified. 15 But the Holy Spirit also witnesses to us; for after He had said before, 16 “This is the covenant that I will make with them after those days, says the LORD: I will put My laws into their hearts, and in their minds I will write them,” 17 then He adds, “Their sins and their lawless deeds I will remember no more.” 18 Now where there is remission of these, there is no longer an offering for sin. (NKJV)
13 And you, who were dead in your trespasses and the uncircumcision of your flesh, God made alive together with him, having forgiven us all our trespasses,
English Standard Version (ESV)
I hope you noticed the last three words in Colossians 2:13 "all our trespasses". The writer of Hebrews says we are "perfected for ever". That is something to sing hallelujah about! Don't listen to the pharisees and hypocrites who desire to water down the work of Christ. If you have believed on the Lord Jesus Christ you are the possessor of "complete" forgiveness!
