When John the Baptist announced “here comes the lamb of God who takes away the sin of the world” he was announcing the successor to all the law and the prophets.
What a few thousand years of Israel’s efforts could not accomplish, the Lamb of God did with one single act. Christ succeeded at what that whole culture with all its wanderings, buildings, feasts and sacrafices was their utter failure to effectually deal with sin. If they had succeeded they would not have had to repeat them. But Christ took away all the sin of the world past present and future, in one fell swoop. He then gifted sinlessness on all who would believe in Him, past present and future. As scripture says “whoever sins has neither seen Him or knows Him” because they have not learned to accept that fact that the power of sin was grounded out at the cross. Every negative feeling, act and all the consequences and ill effects of sins were defused there.
As the successor who supercedes, He expired and rendered a failure all other acts and attempts to take away sin and bring salvation. Christ is now the propitiation for the sins of the whole world for all time without needing to do anything else for this to be true. Without the shedding of blood there is no remission of sin. When Christ’s blood, through the eternal Spirit dripped off His carnal fingertips and his ribcage and forehead to the dirt below, the earth was cleansed.
The superfluous move of the Holy Spirit is not bound by law. Laws are for the lawless. The law of the Spirit of the life that is in Christ Jesus has set me free from the law oof sin and death. The internal dwelling of the Holy Spirit in a believer supersedes and expires the need for any external motivators or controllers. The law is for the lawless (1 Tim )
Those who are focused on sin, including all the confessions and anticipation of somebody ridding the world of sin, has patently rejected “The Lamb of God who takes away the sin of the world”. Many have heard the gospel message, but simply cannot believe that sin has met its final blow. As Christ said at the cross “Father it is finished”.
But many cannot take their eyes off sin and condemnation to recieve a cleansed conscience for eternal life.
To live with a sin based conscience is to live without interaction with God who finished dealing with sin with His Son. Those who reject Him reject life and are the walking dead. They are dead to the things of God but alive to the things of this age.
The sin based conscience walks by sight. Their external senses control them and what they see condemns everything.
Titus 1.15 To the pure all things are pure, but to those who are defiled and unbelieving nothing is pure; but even their mind and conscience are defiled.
