"For I know that my redeemer liveth, and that he shall stand at the latter day upon the earth" - Job 19:25 KJV
"Do not move an ancient landmark or enter the fields of the fatherless, for their Redeemer is strong; he will plead their cause against you." - Proverbs 23:10-11 ESV
'Jesus, the Redeemer, is altogether ours and ours forever. All the offices of Christ are held on our behalf. He is king for us, priest for us, and prophet for us. Whenever we read a new title of the Redeemer, let us appropriate him as ours under that name as much as under any other. The shepherd’s staff, the father’s rod, the captain’s sword, the priest’s mitre, the prince’s sceptre, the prophet’s mantle, all are ours. Jesus hath no dignity which he will not employ for our exaltation, and no prerogative which he will not exercise for our defence. His fulness of Godhead is our unfailing, inexhaustible treasure-house.' - Charles H Spurgeon
We have a redeemer.
A redeemer must have strength. This person must have will and ability to step in and buy back what is lost... to defend the property lines of inheritance.
"And you shall consecrate the fiftieth year, and proclaim liberty throughout the land to all its inhabitants. It shall be a jubilee for you, when each of you shall return to his property and each of you shall return to his clan. That fiftieth year shall be a jubilee for you; in it you shall neither sow nor reap what grows of itself nor gather the grapes from the undressed vines. For it is a jubilee. It shall be holy to you. You may eat the produce of the field. In this year of jubilee each of you shall return to his property. And if you make a sale to your neighbor or buy from your neighbor, you shall not wrong one another. You shall pay your neighbor according to the number of years after the jubilee, and he shall sell to you according to the number of years for crops." - Leviticus 25:10-15 ESV
No land could be lost or sold forever in Israel. The inheritance was fixed. God gave the land to families in tribes and though men had freedom to let it change hands they didn't have the liberty to let it stay that way. God commanded a return of all belongings for each generation.
As you can imagine... if that was truly going to happen someone strong would need to enforce this policy. Among men it was rarely enforced. God however enforces this policy. His children can not sell their birthright. Not forever at least.
As redeemed ones we have a Heavenly heritage. Whatever is truly ours can not be sold or taken for long. The Gospel belongs to mankind as an offer from God to anyone who wants it. Christ is the entrance into a strong tower of defense.
We see outside our door multitudes who need a defender. Children who need someone who will stand in the gap for them or they will be swallowed up by a system that will lock them up and throw away the key.
The world is a place where anything can be bought or sold. Heaven is a place where gifts are given and once entrusted those gifts have a redeemer that defends them.
"Thy kingdom come. Thy will be done in earth, as it is in heaven." - Matthew 6:10 KJV
