Therefore you are no longer a slave, but a son; and if a son, then an heir through God.
We are heir’s of God (one who receives his allotted possession by right of sonship), through our wonderful Savior, Jesus Christ. As sons and daughters of God our inheritance is based on what Christ has done for us, not what we have done, and we receive that inheritance by faith.
One who is a part of a family and given an inheritance is written in the will of that family member. That inheritance is theirs by birthright and it is revealed to them in the reading of the will. God has written us in His will, the will and testament of the New Covenant. We are written in His will because once born again we are part of His family. So every promise He has given to the children of God is a part of our inheritance just waiting for us to claim it.
So go to God’s Word and find out what belongs to you in Christ by spending time reading His will for you. Meditate on those promises until you see them as yours. Then lay claim to them by faith based on what Jesus has done, not what you have done. Don’t let the devil and others talk you out of what belongs to you. It is your inheritance as a son or daughter of God.
