What is an heir in the Bible?
Here's the answer:
Heirs are those who will inherit gifts from the father, also called an inheritance. We are all co-heirs with Christ.
Heirs in the Old Testament normally referred to the firstborn. The heir of the family would receive everything. The heir would receive the birthright as the eldest son. This means that the firstborn would receive everything from their father while the younger siblings wouldn't receive these nice things.
Jesus is the firstborn Son, who came to the world to die for our sins. Through Jesus, we are all co-heirs. Jesus is a gift to each of us as He gives us forgiveness and eternal life with Him. All of God’s children are given great gifts and blessings in Christ.
As co-heirs of Christ, we are adopted into God's family and are eternally loved. We cannot be sure how great of an inheritance we will receive from the Lord, but we know that we will spend eternity with Him. It is a daily blessing to know the Lord and to have salvation through believing in Him. We are all co-heirs to the promises in Christ. These promises are being fulfilled now and some will be fulfilled in the future.
"You have come to the church of God’s people. God’s first and only Son is over all things. God’s people share in what belongs to his Son. Their names are written in heaven. You have come to God, who is the Judge of all people. You have come to the spirits of godly people who have been made perfect" (Hebrews 12:23).
"As his children, we will receive all that he has for us. We will share what Christ receives. But we must share in his sufferings if we want to share in his glory" (Romans 8:17).
"In the same way, Abraham 'believed God. God was pleased with Abraham because he believed. So his faith made him right with God'" (Galatians 3:6).
