Have you ever felt guilty for sins committed before you were saved? Did you steal money or cheat somebody? Are you not assured of your salvation through Christ? My point is if one sin isn’t under the blood of Christ, then no sin is under the blood of Christ. You would have to repay everyone you cheated, apologize to everyone you lied to or harmed in anyway. Obviously there is no way for that to happen. You’ve lost touch with some people, some have passed on and you’ve forgotten some of the things you did. Our Salvation is by God’s Grace and Mercy alone by Faith alone in Christ as we walk according to His commandments. Jesus already paid for your sin on the Cross. If you try to return money or rectify a sin yourself you make the statement that Jesus didn’t pay for your every sin. You are now working for your Salvation instead of resting in your faith.

Consider Isaiah 53
1 Who has believed our report?
And to whom has the arm of the LORD been revealed?
2 For He shall grow up before Him as a tender plant,
And as a root out of dry ground.
He has no form or comeliness;
And when we see Him,
There is no beauty that we should desire Him.
3 He is despised and rejected by men,
A Man of sorrows and acquainted with grief.
And we hid, as it were, our faces from Him;
He was despised, and we did not esteem Him.
4 Surely He has borne our griefs
And carried our sorrows;
Yet we esteemed Him stricken,
Smitten by God, and afflicted.
5 But He was wounded for our transgressions,
He was bruised for our iniquities;
The chastisement for our peace was upon Him,
And by His stripes we are healed.
6 All we like sheep have gone astray;
We have turned, every one, to his own way;
And the LORD has laid on Him the iniquity of us all.
7 He was oppressed and He was afflicted,
Yet He opened not His mouth;
He was led as a lamb to the slaughter,
And as a sheep before its shearers is silent,
So He opened not His mouth.
8 He was taken from prison and from judgment,
And who will declare His generation?
For He was cut off from the land of the living;
For the transgressions of My people He was stricken.
9 And they[a] made His grave with the wicked—
But with the rich at His death,
Because He had done no violence,
Nor was any deceit in His mouth.
10 Yet it pleased the LORD to bruise Him;
He has put Him to grief.
When You make His soul an offering for sin,
He shall see His seed, He shall prolong His days,
And the pleasure of the LORD shall prosper in His hand.
11 He shall see the labor of His soul,[b]and be satisfied.
By His knowledge My righteous Servant shall justify many,
For He shall bear their iniquities.
12 Therefore I will divide Him a portion with the great,
And He shall divide the spoil with the strong,
Because He poured out His soul unto death,
And He was numbered with the transgressors,
And He bore the sin of many,
And made intercession for the transgressors.

Isaiah is prophesying Christ, that He is the sin offering, the lamb led to the slaughter who will justify many. Consider Isaiah 54 and 55 as well, but I won’t post it here. Of course the whole of the New Testament proclaims this very message of Salvation by Grace and Mercy.
Jesus said Himself said “Come to Me, all you who labor and are heavy laden, and I will give you rest.” (Mat 11:28) What rest? Rest from striving for our own salvation by working for it. He says in the next verse “Take my yoke upon you and learn from Me, for I am gentle and lowly in heart, and you will find rest for your souls.” Back in the day a yoke was put on two beasts of burden, like oxen. So Jesus is saying yoke up to me and follow me. I am gentle and lowly in spirit, humble. We walk in the manner of Christ. In other words we are molded in the character and nature of Christ as we press into Him. I just wanted you to consider your salvation, if it is real, you don’t need to do anything beyond trusting Him with whatever measure of faith that you have. If you are feeling guilty, maybe you aren’t really saved.
