The greatest thing God is concerned about is if you know that He loves you. His love for you is not merely contained in day to day emotions based on your performance. His love has been manifested in one act that is the solid foundation from where we can experience his love for us. That act is simply what Jesus has done on behalf of man. We rest our minds in the fact that He has died the death of the law man, the man that seeks righteousness and justification by His works, and that He was resurrected for our justification. With this truth in place we will never run short of righteousness, holiness or any godly attribute because by this truth God makes his dwelling in man and in such a way we see God live in our lives.
In the following scripture we can see the working of this great love which is that we are justified by His faith. His faith brought the justification and our belief in that gives us access into this wonderful truth.
Gal 2:16 Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified.
