A Christians who believes in predestination might think that because he is saved, nothing can prevent him from coming to the end in glory, no matter how he lives. However, the failure of the Israelites who came out of Egypt discredits this thought. Notice the words to this song after they crossed the Red Sea:
“You in Your mercy have led forth
The people whom You have redeemed;
You have guided them in Your strength
To Your holy habitation” (Ex. 15:13).
They understood that God promised to bring them to the “holy habitation” of Canaan. Their song reflected a foregone conclusion that because God said He would do it, it was as good as done. Their words “You have guided them … To Your holy habitation” are definite.
But they all did not make it into the promised land, even though God promised. Hebrews 4:19 supplied the reason: they did “not enter in because of unbelief,” which was shown by their disobedience and murmuring.
What better place to have given the reason as “because they were not predestined to glory.” No, it was their own unbelief, in spite of God’s many striking miracles in their midst, that did them in.
God had foreknowledge of what was going to happen, but it did not benefit the Israelites when they acted in carnality. God had a definite plan that would bring them to the promised land, but it only benefited those who walked in faith and obedience, those who loved God.
1 Cor. 10 applies the lesson of the Israelites, who were redeemed, to Christians. Read 1 Cor. 10 and you’ll see that God was not pleased with all of the people who came out of Egypt because they continued in rebellion and sin. Paul warns us not to take for granted that all of us will come to a good end.
“Therefore let him who thinks he stands take heed lest he fall” (1 Cor. 10:12). Let him who thinks he stands because he’s predestinated based on God’s election take heed lest he fall into rebellion and sin–and suffer the same fate as the Israelites who took it as a foregone conclusion that God was bringing them into the promised land.
