take it into perspective, Adam and Eve were created perfect. And it was so until they decided to be otherwise. as simple as going to a tree. Christians can be fake, do the bible thing if I may say it that way. It is going to be only by the grace of God those who believe and dont sell for short their faith that will be with Jesus when He comes. One must have a very active, alive, relationship with the Lord. WE HAVE THE DEADLIEST ENEMY OF ALL, THE DEVIL, AND HE KNOWS THE BIBLE BETTER THAN YOU AND I. HE KNOWS GOD AND ALL THAT GOD IS AND CAN DO. HE LIVED WITH HIM IN HEAVEN.
Look at Christ, the roll model of all Christians, He had to endure to the end for Him not be lost and take our place on the cross. God wants us not to be just like the average Joe. He created us to be like Him. Let us keep in mind that it was not because of something God did or didnt do that we needed to be saved. Until His death on the cross, the devil had a relentless attack against Jesus so He would not die for our sins. Jesus was born and raised perfect. His faith in the Father until the end kept Him from giving into the devil, being a sinner.
No one is putting aside or saying that Jesus cant do anything against sin. It is that as long as we embrace sin, we are dead, therefore, Jesus cant help us. Remember sin is what gives existence to the devil. As long as we do God's will, the devil is not the one that we are praising with our actions. Our free will is always there. it is the reason why, Eve was tempted and so was Jesus. Unlike Eve, Jesus listened to God's word and did His will.
the blood of the Lamb can not keep us from sinning. It can only redeem us from sin. As long as the devil is alive in our life, because we are sinning, we are eternally dead. As long as Jesus is alive in our life, because we are doing God's will, we have eternal life. This in someway can be interpret as if we can save ourselves. NOOOOO. We can choose to or not be saved until the end. Does it mean that we need to be sin free for Jesus to save us? NOOOOO. We need to rebuke sin and be willing to live sin free and God can empower us to do so.
That is why we are to get over this saved by grace or the law, or being a Jew or a Gentile. it is all about faith, in who do we believe in, God or the devil. Romans 1:17, Habakkuk 2:4 then and only then can John 3:16 be a blessing to us or not.
