Your body comes with a predisposition for sinning. The fall in the Garden of Eden ruined the original genetic code for mankind. Sin corrupted the bloodline. Now running through your flesh is a demonic code that can only be eradicated by a new blood line, by faith through Jesus Christ. Once you receive the Savior, which is Christ the Lord, you still live in the old bloodline. Spiritually, you have been made new, hence a desire to live for Jesus and the awareness of heaven and hell. Unfortunately, death is inevitable as God specifically told Adam the tree in the midst of the garden would kill him, if he chose to eat of the fruit of that tree. He chose to eat the fruit of that tree.
Paul, comes along after the death and resurrection of Jesus Christ and tells us to “fight the good fight of the faith. Take hold of the eternal life to which you were called when you made your good confession in the presence of many witnesses (1 Timothy 6:12). This is the only prescription we have to ensure our salvation. Therefore, my dear friends, as you have always obeyed–not only in my presence, but now much more in my absence–continue to work out your salvation with fear and trembling (Philippians 2:12).
The wrath of God is coming on the children of disobedience. We cannot win against our flesh without a direct assault against our flesh by spending time soaking in the presence of God and being busy doing the Fathers business. Being saved is work. Making sure you make it to the end is going to be difficult.
