Faith demands actions and when faith and actions work together, faith is made complete by what you do! I am reminded of the story of Abraham and his son Isaac in the Bible in Genesis 22 that serves as a good representation of faith and works.
Our faith requires that we walk in trust and obedience to the One who is the Author and Finisher of our faith. God knows best and wants nothing but the best for us. Taking Him at His word and promises helps us to walk in power and authority knowing that He who began a good work in us will bring to marvelous completion.
