Main Course: So this is what the Sovereign LORD says: "See, I lay a stone in Zion, a tested stone, a precious cornerstone for a sure foundation; the one who relies on it will never be stricken with panic. (Isaiah 28:16)
We already have the faith of God (it came with our born-again spirit), it just needs to be exercised.
We already have the mind of Christ (it came with our born-again spirit), it just needs to be renewed.
We already have the spirit of God (it came with our born-again spirit), it just needs to talk/connect with God every day.
If we are lacking anything it is because the Light of God has not shone in that area enough for us to see, recognize that we have already been made whole. Upon this realization, we confess with our mouth and believe in our heart to embrace the grace of God. It will flow into our spirit like rivers of water, and we will drink from that well until fullness has invaded our souls.
Are you fully aware that you already have His life (it just needs your recognition of it and daily affirmation to bring forth its abundance/yield forth the fruit of it)?
