In you lies the faith of God, the faith by which the universe was made lives in you. When God gave us Christ, He gave us all. Everything we need is included in this Christ that now indwells us. All the power we need, all the truth we need (John 14:6), all the grace, all the faith, all the righteousness, all the holiness, all the works, all the love etc. Christ is our all in all.
"That in the dispensation of the fulness of times he might gather together in one all things in Christ, both which are in heaven, and which are on earth; even in him:" (Eph 1:10).
God has gathered together all things into one —Christ —and He has put that Christ in us. Christ is all the faith we need, and to become one with Christ is to be one with the faith of God. On the cross Jesus said it is finished, yet we continue to struggle and struggle. We struggle to grow in faith, all the while the faith that we need already lives in us. We only need to become one with that faith inside of us.
"If we live in the Spirit, let us also walk in the Spirit." (Gal 5:25).
"For we walk by faith not by sight." (2Cor 5:7).
Just as we have the Spirit in us, and therefore we must walk by the Spirit, so also do we have faith in us, and this requires us to walk by faith. All the faith we need is already in us, we only need to be awaken to it and learn to walk by it. We become awaken to this faith through revelation.
You need to have a revelation of Christ your faith. You need to truly see that the faith of God lives in you; the same faith by which the universe was made dwells inside of you. Once you are able to see that with your heart you must come into it, become one with it, and then live from it, or as the scripture will say, walk by it. Walk by the faith you now see in you, express it.
While growing as a Christian I was taught that I needed more faith, so I became anxious on getting more and more faith. Whenever I want something from God, I found myself always wondering whether I have enough faith. Most of the time I wasn't sure; I was not sure whether I have enough faith to get the healing I need, not sure if my faith was enough to get my prayer answered, not even sure if my faith will keep me standing till the end.
I got it all wrong, I already have all the faith I need, I only need to learn to rest in Christ my faith. When I got this revelation I realise that I could just come into the faith of God and pray for healing and it comes speedily. Whenever I find myself filled with doubts I know I have wondered out of my faith (Christ, the faith that lives in me), I simply look inside, see this faith in my heart and come into it, and then the doubt disappears.
There is a way you fix your eyes intensely on something that every other thing is blocked out. I you fix your gaze, it overwhelms you and flood your heart. I could now live above doubt and enjoy the faith of God, it's such a wonderful thing. God has put an end to all of our struggle and has given us rest, we simply need to come into that rest and enjoy the abundance of our Lord.
