The act of material and temporal deliverance or preservation from danger, suffering, sickness or death. Sin isn't just an act or attitude of wrongdoing.
Sin is a state of being.
It is the state of being separated from God. Unfortunately, everyone is born into a state of being separated from God due to the rebellion and disobediance of our original parents, Adam and Eve, in the Garden of Eden, as recorded in Genesis chapters 2 and 3. God knew of humanity's need for salvation, so a way was devised by which the human DNA could be purified. He is God's remedy for the sin problem. He suffered and died a horrible death by being beaten, scourged and then finally nailed to a cross until all of His blood ran out.
