For natural faith, the tithe has nothing to do with marriage.
But from the point of view of the Bible, for supernatural faith, the two are associated.
Tithes are the basis of a relationship with God.
They are the first fruits, the first of everything placed on the altar in recognition of the supremacy of the Lord Jesus in our lives.
They are a sign of our covenant, pact or marriage with Him
A wedding ring symbolizes commitment to another person. Likewise, the tithe symbolizes commitment to God and is a type of Jesus, Mediator of a New Covenant between the Creator and those He created. Hebrews 9.15; 12.24
A tither becomes the tithe itself, just as Jesus was the Tithe of God for humanity. Jeremiah 2.3
Tithes and offerings were a required condition for the return of Jacob’s descendants to God.
“…Return to Me, and I will return to you, says the Lord of hosts. ‘But you said, “In what way shall we return?”
Will a man rob God? Yet you have robbed Me! But you say, “In what way have we robbed You?” In tithes and offerings.
You are cursed with a curse, for you have robbed Me, even this whole nation.’” Malachi 3.7-9
Tithes establish a partnership with the Lord of Hosts.
In addition to this, a tither proves to himself, to the world and to the instigator of the curse that his faith in the Living God is not a farce.
There’s no other way. Those who want the Seal of God, the Guarantee of the Spirit, Peace, Joy, Love and Life must join forces with the Almighty God of Abraham by means of faithfulness in their tithes.
If not, they will continue to live for the sake of living—a life of mediocrity.
