The author of the book of Hebrews tells us that the only unforgivable sin is unbelief. It is echoed all over the Bible. For God so loved the world that He gave His only begotten Son that whosoever BELIEVES in Him shall not perish but have everlasting life {John 3:16} This is the Gospel; the Good News for anyone who believes.
What is the one thing that
keeps people from believing? Their sin. That's it. Take
heed, brethren, lest there be in any of you an evil heart of unbelief, in
departing from the living God. But exhort one another daily, while it is
called To day; lest any of you be hardened through the deceitfulness of sin
{Hebrews 3:13} Sin hardens our heart. The more we sin, the farther from God we
get. The farther from God we get, the less we believe in God, then God gives us
over to a reprobate mind {Romans 1:28}.
Hebrews
exhorts us several times not to harden our hearts to Truth. How do our hearts
become hard? By flirting with sin and giving it a foothold into our life. By watching shows, movies, or reading books with sexual immorality, immodesty, and debauchery. Romans 1:32 warns us Who knowing the judgment of
God, that they which commit such things are worthy of death, not only do the
same, but have pleasure in them that do them. We should NOT take pleasure in
other's sinning, since this is giving Satan a foothold into our life.
We must
protect our heart. Above
all else, guard your heart, for everything you do flows from it {Proverbs
4:23}. We are commanded to dwell on the lovely and the good for a reason; what
we watch and read affects us and begins to harden our hearts. Once we harden our hearts
through the deceitfulness of sin, we may not enter into eternal life since a
hardened heart leads to unbelief. And to whom sware he that they should
not enter into his rest, but to them that believed not? So we see that
they could not enter in because of unbelief {Hebrews 3:19}.
You
cannot be a Christian and walk in sin. It is impossible. Read and study 1 John
and it is very clear. Be transformed by renewing your mind with the Truth. Be
in the Word consistently. Listen to godly preaching and teaching. Obey God and
don't allow your heart to be hardened. You have been warned.
