All that God is, accessed by faith in Jesus Christ, and made manifest in us AND around us by the indwelling and empowerment of the Holy Spirit - which we steward for His purposes and glory.
We have been made right with our Father through Jesus. And because we have a father? We have an inheritance.
One of the most PROFOUND things that took place at the cross, and then in Jesus' resurrection and ascension into Heaven, is the fact that we become joint-heirs with Christ.
