In a world where love is often temporary and fleeting, we can take heart that God's love does not operate in that realm. His love endures forever.
He loves us yesterday, today, and tomorrow. Like a good parent, love for a child is not based on performance or behavior. It is solely founded on the truth of who the child belongs to. God is our Father. He loves us because of who He is.
This should bring an overflow of thanksgiving from us and security in what we believe.
