What does it mean that God is “FOR US”?
The goal of grace is to create a love relationship between God and us who believe the kind of relationship we were first made for.
The revelation of the New Testament is that God is our heavenly Father, we are His children and He is “FOR US”. We could say that how well a person understands Christianity is related to how much he makes of the thought of being God’s child, and having God as his Father. If God being your Father doesn’t motivate, and control your worship and prayers and your whole outlook on life. You don’t understand Christianity very well.
God being for me has nothing to do with my ability, my performance, or my obedience. Once you set qualifications for God being for you, you have left grace and have put yourself back under the law. If you don't know or believe that God is for you because of what God decided about you in eternity past and then sent his own son to become a man and take your place, pay for your sins on the cross and rise from the dead to secure your justification and secure your place in the Father's family. Then you don't really know the God of the bible and you will live in fear and insecurity. I get up every day thanking God that he is for me!
