You receive a special inheritance when you make the decision to follow Jesus; first He makes you a new Creation, filling you with His Spirit.  That is the first installment, or the first payment of the grand eternal life that you will live with Him in heaven.

It is through the spirit that you receive all spiritual blessings to enjoy and have right here on this earth, but you have to receive them by faith.  Being granted authority is a gift from God for you; it is a spiritual blessing awaiting you when become a child of God.  Why wait to live in victory?  Why let the devil push you around and rob you of the inheritance promised to you?  Stand your ground.  Hold on to the Word of God and His promises for your life.
