Hebrews 3:12-15

121Take care, brethren, that there not be in any one of you an evil, unbelieving heart 2that falls away from 3the living God. 13But 4encourage one another day after day, as long as it is still called “Today,” so that none of you will be hardened by the 5deceitfulness of sin. 14For we have become partakers of Christ, 6if we hold fast the beginning of our 7assurance firm until the end, 15while it is said, “8Today if you hear His voice, Do not harden your hearts, as 9when they provoked Me.”
