The Fall and Sin of Man ruined God's perfect plan...

I look at the effects of all SIN this way...

In the Garden of Eden before the fall there was no Rot or Rust, and God walked daily in the Garden with Adam and Eve. The Garden was God's perfect dwelling place on earth. After the sin we were separated from God, and the rot of sin, and the rot of nature entered the world, once it became about "ME" and "US" and not God.

God by his Grace gives us a way to escape the Rot of sin... but we have to leave ALL things that God calls sin behind…We need to seek that personal relationship with God, it is by God's grace alone that we leave sin behind.

Also it is not up to us as Christians to judge a person’s actions, God’s is the judge of our faith and sin. All we can do is point out in love what sin is, pray that God opens the eyes for the sinner to see their error, do our best to live as an example using Christ as our model, and let God sort us all out in the end.

II Tim 4:21 Do your best to present yourself to God as one approved, a workman who does not need to be ashamed and who correctly handles the word of truth.

Romans 12: 1-2 Therefore I urge you brothers in view of God's mercy, to offer your bodies as living sacrifices, holy and pleasing to God...This is your spritual act of worship. 2 Do not conform anylonger to the paterns of this world, but be trasformed by the renewing of your mind. Then you will be able to approve and test what God's will is. His good pleasing and perfect will.
