Men get angry and even if they do not forgive, they cool down given enough time, likewise men love but in time their love diminishes. God is different!
“And I will bring an everlasting reproach upon you, and a perpetual shame, which shall not be forgotten.” Jeremiah 23:40
“The LORD has appeared of old unto me, saying, Yes, I have loved you with an everlasting love: therefore with loving-kindness have I drawn you.” Jeremiah 31:12
If we understood the previous words to be spoken by men, we would partially believe them because we know that men cannot do anything forever. When the Everlasting God makes a statement that He will never forgive, or His love is Everlasting that is exactly what He means and what will happen. God possess the power, will, and character to hate and love forever, His sense of justice will never cool down, and His loving passion will never chill!
The Christian understands that He is loved eternally because of who God is and what He has promised.
“So when God wanted to give the heirs of his promise an even clearer demonstration of the immutability of his purpose, he intervened with an oath, so that by two immutable things, in which it was impossible for God to lie, we who have taken refuge might be strongly encouraged to hold fast to the hope that lies before us.” Hebrews 6:17-18
It is unimaginable to think of God’s anger never ceasing and without any hope of reprieve.
“Therefore, knowing the fear of the Lord, we persuade men…” 2Corinthians 5:11
