Hebrews 3:12–13 (NKJV)
12 Beware, brethren, lest there be in any of you an evil heart of unbelief in departing from the living God; 13 but exhort one another daily, while it is called “Today,” lest any of you be hardened through the deceitfulness of sin.
Note that calls an unbelieving heart an evil heart. One of the solutions to the danger of slipping away into an attitude of unbelief is that we as Christians should be exhorting one another daily. Usually we only get to see each other once or twice a week and then it is usually very superficial. We need to be involved in one another’s lives in such a way that we can stir one another up to love and good works.
