Salvation was not intended to just benefit you after death. Salvation is intended to benefit you from the moment of salvation all the way through eternity.
God from the very beginning, wanted creation to listen to His words, to use His stuff the way He intended His stuff to be used. We didn’t. Man rebelled. Creation fell. God became flesh and became the only human who ever fully listened to God. We killed Him; yet through this death He demonstrated His power by resurrecting.
When we place our faith in Jesus Christ, who died and rose again, by faith we identify ourselves with His death, burial, and resurrection. We are raised up to newness of life, born again, made partakers of the divine nature, and other awesome ways of saying it!
In our new, spiritual creation self, we can actually obey God! We can do good! This is, in fact, the one way to know you are saved–good works show up.
God created us in Christ Jesus for the purpose of doing good works (Ephesians 2:10). The grace of God that brings salvation also teaches us to deny ungodliness and worldly lusts so we would live soberly, righteously, and godly in this present world (Titus 2:11,12). He redeemed unto Himself a peculiar people zealous of good works (Titus 2:14).
Here’s another way Paul put it:
For God hath not called us unto uncleanness, but unto holiness.
–1 Thessalonians 4:7
Once again we see that the point of salvation is so we would be changed to do different stuff. In the flesh we were doing all manner of unclean things. But now, after we are saved, we are to practice holiness.
Holy living is what you were called to do! Holiness is what salvation is for!
There is no other reason for salvation than being new creations who do God’s will.
Paul follows up with 1 Thessalonians 4:8:
He therefore that despiseth, despiseth not man, but God, who hath also given unto us his holy Spirit.
Whoever despises this holy calling despises God Himself and the HOLY Spirit He can put in us to enable us to do holy things.
There are a lot of people teaching Christians that what they do doesn’t matter. That sin is ok, God loves you so don’t worry about it. There is a lot of false teaching on this issue.
Anyone who teaches that salvation does not lead to holy living is despising God Himself and the work of the Holy Spirit.
The idea that Christ died so we can sin the rest of our lives and then go to heaven seems rather silly. Why would we want to live in the stuff that Christ died for? If we are dead to sin, why live any longer therein?
The Gospel re-creates us, sets us free from the power and bondage of sin, and equips us to every good work. You know you are saved when there is ample evidence that you’ve been created in Christ Jesus. Your whole life is different. Old things are passed away, behold, all things have become new!
There’s a new mindset. New priorities. New rules and new behavior. This is not optional; this is what happens when you are born again and placed into the Body of Christ. Happens every time.
God has called you for the purpose of being holy. Be holy for He is holy. The Gospel equips you for this. You’ve got everything you need; go use it!
