This is used in various applications as of one coming into a possession. It is applied to the Lord when He came to Israel seeking fruit. They said in effect, “This is the heir: come let us kill him, and the inheritance shall be ours” (Mark 12:7). Christ is appointed by God to be heir of all things (Heb. 1:2). Believers are by grace made sons through Christ, hence heirs, heirs of God, and joint-heirs with Christ (Rom. 8:17; Gal. 4:7: Compare John 17:22).
