(heirship). [HEIR.]

“Heir” From Concise Bible Dictionary:

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).

“Inheritance” From Concise Bible Dictionary:

The land of promise is constantly spoken of as the inheritance of Israel: the land flowing with milk and honey was given to them by God (Deut. 4:21; Psa. 105:11, and more). So when Israel returns to take possession of the land in a future day, it is still called their inheritance (Ezek. 45:1, and more). This all shows that they were and will be an earthly people, but God blessed them on earth in relationship with Himself as Jehovah, and will again bless them on earth when they own the Lord Jesus as their Messiah. In connection with this God calls Israel His inheritance: He hath chosen them for His own inheritance (Psa. 33:12; Psa. 78:62, and more).
The Christian has no inheritance on earth; his inheritance is with the saints in light (Col. 1:12): an inheritance incorruptible, and undefiled, and that fadeth not away, reserved in heaven (1 Pet. 1:4). In the meanwhile the Holy Spirit is given as the earnest of the inheritance (Eph. 1:14). It is in Christ Himself the inheritance is obtained, for the Lord Jesus will possess all things in heaven and in earth (Eph. 1:18).
