It is difficult, but not impossible

"...while we do not look at the things which are seen, but at the things which are not seen. For the things which are seen are temporary, but the things which are not seen are eternal." 2 Corinthians 4.18

If the person who is born of the Holy Spirit may find it hard not to heed to the lures of what your physical eyes see, imagine when you are not born of God. It is difficult, but not impossible. You really have to want it. But therein lies the secret of how to walk with God and the meaning of living by faith.

A UNION OF HELL

"Do not be unequally yoked together with unbelievers. For what fellowship has righteousness with lawlessness? And what communion has light with darkness?"    2 Corinthians 6.14

The union of a person that is born of the Spirit with a person that is not born of the Spirit has led to many disillusions in the faith.
Only a very few people that are faithful avoid having relationships with unbelievers.
They are under the impression that this person will eventually convert to God, but this goes completely against the Word of God and brings curses upon them.
It's like putting good fruit with rotten fruit in the same basket. The good fruit doesn't cure the rotten fruit, but the rotten fruit will destroy the good fruit.
