If, then, we are children, we are also heirs: heirs indeed of God, but joint heirs with Christ, provided we suffer together that we may also be glorified together.”​—Rom. 1:7; 8:14-17.

In accord with what God’s spirit thus indicates, their minds and hearts become set on the prospect of being joint heirs with Christ, and they accept the responsibilities of God’s spiritual children.​—Phil. 3:13, 14.
