Bitterness is a bad master! Bitterness is a life wrecker! Bitterness grows the fruit of death! Let's face it, bitterness has destroyed more homes, more relationships and split the church! Bitterness brought a railing judgment against Simon from the apostle Peter as his heart was not right before God and if possible the intention of his heart would be forgiven (Acts 8:20-23). That's a scarey thought. Simon pleads with Peter to pray for him.
"See to it that no one comes short of the grace of God; that no root of bitterness sprining up causes trouble, and by it many be defiled; that there be no immoral or godless person like Esau, who sold his own birthright for a single meal." (Heb. 12:15-16)
The grace of God is powerful that gives us the ability to live beyond us. God's grace strengthens and provides more than we can even imagine. Without the grace of God, salvation doesn't exist and our lives are reduced to living just like mere men. God's grace toward us in Christ Jesus simply put is the ingredient that causes us to live in Him and is always greater toward us than any sin.
Bitterness cancels the grace of God! The results of bitterness in the heart of a person shuts out God's involvement with us. Bitterness satisfies the angry heart. Bitterness leads one to trying to let others know how they have been wronged and how upset they are to destroy the one with whom they are bitter. Bitterness that stays in the heart long enough, it will create such hardness and callouses beyond degree that you may never be reached by grace again. Bitterness is a deceiver making people think they are doing right with the Lord while their heart is fueled by its standard. Bitterness is a bad deal and worst of all, it does cancel the grace of God!
