Our behavior betrays our belief in the promise. If we know that God is working for our good and that all things work out for our good then we should not worry. The promise gives us access but we also have a responsibility and have to apply effort to get hold of the promise. There is an eligibility clause we need to fulfill before we can access the promise - love of God. The love of God is different from expressions of love. The love of God is not meeting his needs, loving his gifts or the things he prompts us to do. But the love of God is an internal intangible disposition of heart.
