“Looking unto Jesus the author and finisher of our faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God.” (Hebrews 12:2)
“…the author and finisher of our faith…” God creates and gifts us with the faith needed to believe in Him and repent of our sins (authors), and God maintains, grows, and feeds our faith, keeping it alive within us throughout our walks in this life unto the death that allows us to enter into life eternal with Him in Heaven (finishes).
Not one single bit of it comes from us, all is of and from God, an indescribable gift of mercy, compassion, and love. For love He descended into time and walked among us. For love He suffered derision, false attacks, imprisonment, and torture unto His physical death on the cross. For us He did this, and it brought Him JOY to fulfill the will of the Father by doing so.
We can love Him, only because He first so loved us (1John 4:19).
