The following is found in Bishop Moule's Thoughts on Union with Christ, and has been a mainstay of my life for decades:
A MORNING “ACT OF FAITH.”
I believe on the Name of the Son of God.
Therefore I am in Him, having Redemption through His Blood, and Life by His Spirit.
And He is in me, and all fulness is in Him.
To Him I belong, by purchase, conquest, and self-surrender.
To me He belongs, for all my hourly need.
There is no cloud between my Lord and me.
There is no difficulty, inward or outward, which He is not ready to meet in me to-day.
The Lord is my Keeper. Amen.
