Sin is man's captor and slave owner

Every human being born since the Fall has come into the world enslaved to sin,under total bondage to a nature that is corrupt,evil and separated from it's Creator.No person is spiritually free.No human being is free of sin or free of it's consequences,the ultimate consequence,or penalty, for which is death (Rom 6:23)."The soul who sins will die"(Ezek 18:4)

Jesus said,"Truly,truly,I say to you everyone who commits sin is the slave of sin"(John 8:34),and Paul points out that every person has commited sin:"There is none righteous,not even one"(Rom 3:10;cf Ps 14:1).In the same letter the apostle says that we are all "sold into bondage to sin"(7:14) and that,in fact,the whole of creation is enslaved to the corruption of sin(8:21)

Sin is man's captor and slave owner,and it demands a price for his release.Death is the price that had to be paid for man's redemption from sin.Biblical redemption therefore refers to the act of God by which He Himself paid as a ransom the price of sin.
