Exodus 32:14
“And the LORD repented of the evil which he thought to do to his people.”
We see in this verse that the intercession of Moses earlier (v.11-13) was effectual. In answer to the prayers of Moses, God showed his purpose of sparing the people (as he had before seemed determined on their destruction). This change in the outward appearance of his purpose is called, repenting of the evil.
“God is not a man that he should repent” (Numbers 23:19). He "knows the end from the beginning” (Isaiah 46:10). When he threatened to destroy Israel, he knew that he would spare them; but, as he communicated to Moses, first, his anger, and then, at a later period, his intention to spare them, he is said to have "repented."
Just as Moses made intercession for Israel to God then, so Jesus makes intercession for us to God now.
We can’t change the mind of God, His ways are above our ways and we are not His counselor. However, we can pray for His will and be in agreement with His ultimate will, knowing Jesus will intercede for us.
The Truth
“Therefore He is also able to save to the uttermost those who come to God through Him, since He always lives to make intercession for them.” (Hebrews 7:25)
