Isaiah 55:3 3 Incline your ear, and come unto me: hear, and your soul shall live; and I will make an everlasting covenant with you, even the sure mercies of David.
Can you imagine having someone to be eternally loyal to you, someone to love you forever? For most of us, even the thought that there is an eternity just blows our mind. We can’t imagine our self being 80 years old which is much less living forever and ever and ever. But our God loves so much that he promises not only to let you live with him forever, but to love you and be loyal to you. That’s the friendship our God have for us.
God has so much confidence in who you are, who he made you to be, that he want to spend forever with you. Even if your friend had desert you, he would still love you. If you did something and hacked off everyone you know, he would be loyal to you. God has not committed himself to you for the length of your life but length of his life i.e for the eternity.
