By grace (receiving what we did not deserve through faith in Christ) we have been declared righteous (justified), and made heirs. Having been made righteous (right with God), we are His children and therefore we now have a right to all that Christ has provided for us. When someone passes away they have a will. That will determines who will receive what that person had given to them as a part of their inheritance. Jesus having died for us provided to all who become a part of God’s family through being born again an inheritance. He wrote it in His will, the New Testament. If someone receives an inheritance from another person they have to claim that inheritance. So it is with what Christ has provided for us. He has given us in His will what we now have a right to, but we have to claim our inheritance. We don’t earn it, it already belongs to us, but we claim it by faith in His written will. Take time to read and meditate on His will for you and claim by faith what you as a child of God now have a right to.
