What are some of Satan’s most successful strategies in dealing with followers of Christ that you have noticed? ?

By making it seem that our sinful actions against God’s commandments has no consequences. According to 1 Corinthians 6:9,10 it shows that those who practice sexual immorality, idolatry, adultery, & etc will not inherit God’s Kingdom. 

Satan can manipulate our thoughts merely by causing a series of ill things to happen that cause many Believers to lose confidence and faith in God.  Satan can cause us to doubt, confuse us, cause us to be depressed, unhappy, angry...Satan can enter a marriage and cause a couple to distrust each other for absolutely no reason, cause them to disconnect and stop communicating or even hate...Satan can cause us to doubt our own selves and once we begin on that path, we begin to doubt God.  Satan  can cause us to lose confidence in our own selves that distance us from God. 

Satan can tie up our lives with useless things that absorb all our time so that we have less time to spend with our LORD, God...Once we begin to distance or separate our lives from God, God distances his blessings and works from us.  If he's not in our minds, God is not in our lives 

By getting you to perceive the Kingdom of God outside of yourself by making Sin look like a hurdle to overcome, Sin exist at the level of the mind which invented the separation from God in the first place, Jesus was clearly trying to show us how to undo what we created by seeking things from a different angle, our minds don't work to the function of the spirit, it works for the benefit of the body, that's why its so easy to accept fear in place of salvation...Luke 17:21 The Kingdom of God comes not by observation, for behold, the Kingdom of God is within you.

That's not a misquote because there are many areas in the Bible that support just that, When your eye be single, your body will fill with light...what light? God's light! 1st John say's God is Light! The Kingdom Within!

The first lie was from the serpent in the garden of Eden.  Satan called into question the word of God.  Doubting His word is what led to the fall.  Satan still delights in casting doubt on the word of God, for believer and non-believer alike.

The most successful strategy foisted on those who believe in Satan is the belief that there is an imaginary being called Satan unwittingly foisted upon themselves.

Self righteousness. Luke 18:8

Charles Darwin's false theory of evolution is a prime example of one.

The most successful strategy is implanting the Jesus story into the mind of Paul.

But it's easy to overcome that.  The Jesus story is totally bizarre and anyone who believes it has a screw loose -- and some use puppets to convince themselves that they are right.

Fear is a useful tool to those with bad intentions.

Go to a schizophrenic forum, you would get alot more answers there.
