Later Jesus appeared to the Eleven as they were eating; he rebuked them for their lack of faith and their stubborn refusal to believe those who had seen him after he had risen. (Mark 16:14)
The LORD said to Moses, “When you return to Egypt, see that you perform before Pharaoh all the wonders I have given you the power to do. But I will harden his heart so that he will not let the people go. (Exodus 4:21)
Today, if you hear his voice, do not harden your hearts as you did at Meribah, as you did that day at Massah in the desert… (Psalm 95:8)
As has just been said: “Today, if you hear his voice, do not harden your hearts as you did in the rebellion.” (Hebrews 3:15)
God can harden the hearts of people and people can harden their own hearts as well. The result is not a good thing in either case. The question is, how can believers avoid this?
We must be sure to follow God’s first commandment, “Love the Lord your God with all your heart and with all your soul and with all you mind.” (Matthew 22:37)
