In Numbers 14, there was a turning point. God’s patience had been exhausted by a people who had seen his greatness and goodness, yet obstinately refused to listen and obey his will and refused to trust him.
But Moses raised a valid point. If Israel was destroyed, as it deserved, then the nations would hear of it and say “Because the Lord was not able to bring these people into the land he sware unto them, therefore he hath slain them in the wilderness,” (Numbers 14:16). Israel’s destruction would, therefore, precipitate blasphemy of God’s name.
Instead of destroying Israel, God disciplined his people with a walk in the wilderness. Those who refused to listen and obey God fell there.
In Isaiah 48, God told rebellious Judah he would again discipline them for the same reason: their stubborn refusal to listen had caused them to fall in a strange land (Isaiah 48:11ff).
God wants people who are willing to listen. Jesus said, “Why call ye me Lord, Lord, and do not the things which I say?” (Luke 6:46).
Heaven will only be populated with people who have proven in this world they are willing and ready to hear God and obey him.
