Here are the basics of my belief.
Jesus Christ is the Word of God.
He was made flesh to die for the sins of the world.
When we repent and believe in His finished work on the cross, for our justification, we are saved.
Then He moves in, and lives in and through us, and this life that He lives in us, is displayed by love, joy, peace, longsuffering, peace, patience, kindness, brotherly love and the list goes on, for all things good, come from God.
If a person does not display these fruits, they are most likely not yet made new. His life is displayed through the new creation that He has made us, and as we submit to Him, and His Will, they are displayed in our life, to the world, so God can receive the glory. This new creation is the new covenant, where love has replaced the old system, that could not make nothing perfect.
