The devil’s plan is simple:
He will get you to hate someone usually by planting a seed of envy in us toward that person.
Because anyone who ‘hates’ his brother or sister then does ‘not’ abide in Christ’s Love resulting in ourself being disqualified from the reward of ‘age-during life’ as the verse below states literally:
“Every one who is hating his brother — a man-killer he is, and ye have known that no man-killer hath life age-during in him remaining,” (1 John 3:15)
There are ‘no haters’ who have ‘age-during life’ belonging to His Kingdom.
Everyone decides for themselves.
This point alone is enough to nullify us from getting the reward of ‘life in the coming age’ unless the Lord shows Great Mercy.
