There is great comfort in knowing that you are wanted by God. When people feel wanted and loved, they are relaxed. They are not constantly trying to prove themselves. God is not going to stop loving us at some point. Therefore, we have confidence and trust in his infinite, unchanging, undying love.
Human love is finite.
It can change quickly. It is far more fickle than God's love for us. God's love has stability. We can count on God's love. This kind of love is catalytic to the Christian life.
