There is a relative connection to God's love when we conduct ourselves well, obey his commands, and work with excellence. But, what happens when you stumble, when you had a bad day, or when you have considered cursing God and yourself for the life you have. Can you still believe and know that there is no change with God's love?
It is entirely unconditional, we just have to believe it, and remember there is no changing with God's nature and character. He is a father and he knows and loves us even in spite of our weaknesses.
