“Heirs of God, and Joint-Heirs with Christ”
16 The Spirit itself beareth witness with our spirit, that we are the children of God:
17 And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together.
Elder Bruce R. McConkie wrote:
“A joint-heir is one who inherits equally with all other heirs including the Chief Heir who is the Son. Each joint-heir has an equal and an undivided portion of the whole of everything. If one knows all things, so do all others. If one has all power, so do all those who inherit jointly with him.”
