If you really want to receive the remission of sins, then all that you have to do is just believe in what the Lord has done for you.
It’s when you believe in the Lord’s work of salvation that you can receive the true remission of sins.
Exactly how should you believe in the Lord’s work to reach your salvation then?
You must believe that you were born in sin and that Gods righteous judgement should have been to be passed on you, however out out His love you you, all your sins and judgement were passed onto the Lord through His baptism that bore them all, He died on the Cross in your place, and that He arose from the dead in three days.
When you realize and believe that all your past, present and even furture sins were passed onto Jesus when He was baptized by John the Baptist, and that they were atoned for on the cross, all your sins are indeed washed away on account of this faith.
If you really want to receive the remission of sins, then you have no other choice but to believe in the gospel of the water and the Spirit.
All your sins must be passed onto Jesus for you to receive the remission of sins; unless your sins are passed onto the Lord, it’s completely useless to believe in Jesus no matter how strong your faith might be. You can believe in Jesus all you want, saying, “Jesus is my Savior. I am a sinner. Jesus died on the Cross out of His love for me. He has saved me like this,” but this cannot bring the true salvation of the remission of sins to you.
For you to really receive the remission of sins, all your sins must be passed onto Jesus through His baptism. And you must believe in the condemnation that Jesus bore on the Cross by shedding His own blood for you. Only when you thus receive the true remission of sins by the water and the Spirit, can you finally say with every conviction that you have no sin.
