Then he said to the multitudes that came out to be baptized by him, "Brood of vipers! Who warned you to flee from the wrath to come? "Therefore bear fruits worthy of repentance." Luke 3:7,8
Jesus Christ came to earth, stepped out of Heaven's splendor, clothed in flesh as God among His people to bring the good news of salvation. From the time of the garden of Eden when Adam sinned, a curse has traveled down the bloodlines of all of mankind, a generational curse of sin, thereby staining the souls of all men making them sinners at birth.
John the baptist proclaimed the coming of the Lamb of God who would take away the sins of the world, telling people to repent of their sin and be baptized into death in a watery grave to be resurrected as new creations in Christ, looking forward to the cross of Christ yet to come. As the multitudes came out to be baptized John saw that many were only coming for another religious ceremonial cleansing, as many do today, thus he called them a brood of vipers and told them to repent!
The acknowledgement of ones sins brought about by the conviction of Holy Spirit's voice piercing our conscience brings us to repentance, which in turn allows grace to open the door of salvation, thus the mercy of God, through the shed blood of His Son, cleanses us from all unrighteousness. Without confession of ones sins and repentance, the turning away and changing of ones mind, there can be no salvation.
This is a faithful saying and worthy of all acceptance, that Christ Jesus came into the world to save sinners, of whom I am chief. However, for this reason I obtained mercy that in me first Jesus Christ might show all longsuffering, as a pattern to those who are going to believe on Him for everlasting life. I Timothy 1:15,16
Your servant in Christ, Tim Laughlin
