Do you have within you a sinful, unbelieving heart that is turning you away from God?

Be careful. The heart is deceitful, see that you are not hardened by the deceitfulness of sin and turn away from God. Plead with Him for mercy. For if you put your hand to the plough and turn back, if you make a decision to follow God and turn again to sin and the evil way, your end thereof will be destruction. Be careful to walk fully in the ways of the Lord, and remain true to him.
