John 3:16 corroborates Isaiah 54:8, “God so loved the world that he gave his only begotten Son.” The love of God operates in perfect harmony with the will of God to give his only begotten Son. This means that God does not fall in love, but God wills in love. Paul wrote that “in love, he predestined us for adoption through Jesus Christ, according to the purpose of his will” (Eph. 1:4-5, ESV). It is in God’s love that he predestined his elect according to His will. Hence, God does not fall in love, but God sets his love for his elect. God decides to love us because He wills to love us.
Thus, Yahweh can say these words in vv. 9-10.
9 “This is like the days of Noah to me:
as I swore that the waters of Noah
should no more go over the earth,
so I have sworn that I will not be angry with you,
and will not rebuke you.
10 For the mountains may depart
and the hills be removed,
but my steadfast love shall not depart from you,
and my covenant of peace shall not be removed,”
says the Lord, who has compassion on you.
Yahweh will not pour his wrath against Israel, in the same way that he poured his wrath on the world in the days of Noah. He will not be angry with Israel anymore. He will not rebuke Israel anymore.
