Give thanks to the Lord, for He is good; For His lovingkindness is everlasting (Psalm 136:1 NASB).
God’s love never ends. God’s love lasts forever.
Forever is a long time. When I was in college, in Math for Teachers, we were discussing infinity and how to explain the concept. How could we show the abstract idea?

Infinity never ends. But we’re on this earth that has a beginning and an end. We live in bodies that have a beginning and an end. Nothing on this planet lasts forever. Nothing in our lives lasts forever.
Except God. He’s forever, without beginning or end. But how can we grasp what that means when everything around us eventually ends?
In our class, we took a piece of paper and cut it in half. We cut one of the halves in half. Then one of those in half. And again and again until the piece we needed to cut was so tiny that our scissors couldn’t manipulate it.
And we saw that the paper would never end — until it was thrown away, but that was beside the point for this exercise. If we had the right tools, we could keep cutting the paper forever.
It’s not a perfect analogy, but it makes a point. God not only is infinite, but He also never changes. He doesn’t get cut in half like the paper. Neither does His love.
He is always the same. And no matter what, He’s with us forever. His love lasts forever.
That’s a pretty good deal. We fail. We run out. But He doesn’t.
He is good. He is the God of gods, the Lord of lords. His lovingkindness is everlasting.
