Original sin does not refer to Adam’s first sin, but to the effects and consequences that his sin has had on all humanity. As descendants of Adam, we have inherited a sin nature (Inherent Sin). We are born into sin (Ps.51:5). The inclination of our will is now against God and for sin. There is no ability in us to desire the true God, to incline ourselves to Him, or to produce an authentic desire for Christ (Radical Depravity). In short, we are dead. The same guilt that Adam incurred is passed on to us (Gen.6:5, 8:21; Ps.14:1-3, 51:5; Isa.48:8, 64:6; Jer.17:9; Rom.1, 3:10-20, 5:12-14).
If God does not intervene in the life of the sinner there is no hope of salvation. He must act. In His Mercy, God makes us alive in Christ. He draws us to His Son for salvation. Granting us faith and repentance that leads to life, we willing trust in Jesus for our salvation. Jesus called Lazarus out of the grave, “come forth”. He calls us out of spiritual death into life, “Come to Me!”
God, being rich in mercy, because of the great love with which he loved us, even when we were dead in our trespasses, made us alive together with Christ—by grace you have been saved (Eph.2:4-5)
