Can you really not sin?
Many folks today insist that sinning is inevitable and pretty much unavoidable.
They are convinced that a believer cannot go on without sinning.
They believe that even when living in unrepentant, wilful sin, that God will still present that person faultless before Him.
After all God's word literally says that He is able "to present you faultless before the presence of his glory with exceeding joy" in Jude 1:24. But wait, there is more to this. Something is being left out. In the very same verse it says "Now unto him that is able to keep you from falling". It is a fact, God can keep us from falling He said so Himself.
We can avoid sin and we should believe God's own word regarding this. Now unto him that is able to keep you from falling, and to present you faultless before the presence of his glory with exceeding joy,  To the only wise God our Saviour, be glory and majesty, dominion and power, both now and ever. Amen. Jude 1:24-25 Side note: we can absolutely do all things through Christ which strengtheneth us. I can do all things through Christ which strengtheneth me. Philippians 4:13 Bonus side point: With God all things are possible. ...with God all things are possible. Matthew 19:26, Mark 10:27, Mark 14:36, Luke 18:27 We must also remember that all sin should be confessed and repented of, without exception.
Any remission of sin through the blood of Jesus Christ is for past sins and not future ones. Being justified freely by his grace through the redemption that is in Christ Jesus:  Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God;  To declare, I say , at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus. Romans 3:24-26 I tell you, Nay: but, except ye repent, ye shall all likewise perish. Luke 13:3 But if ye will not so, behold, ye have sinned against the Lord: and be sure your sin will find you out. Numbers 32:23 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. 1 John 1:9 My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:  And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world. 1 John 2:1-2 So share these verses with your humanist pastor or friends when they try to tell you that you are only human and that you cannot avoid sinning. Ok, a few more verses to further drive this truth home... There hath no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it. 1 Corinthians 10:13 ...go, and sin no more. John 8:11 ...Behold, thou art made whole: sin no more, lest a worse thing come unto thee. John 5:14
