In the Kingdom of God, giving is an act of worship and obedience that reflects our trust in God's sovereignty and provision. Malachi 3 emphasizes the importance of bringing tithes into the storehouse as a means to support the work of God and to open the windows of heaven for blessings. This principle of giving is rooted in the example of Abraham, who paid tithes to Melchizedek, recognizing his priesthood and honoring God. Melchizedek, a figure of both king and priest, is a type of Christ, who is declared in Hebrews 5-7 to be a high priest forever in the order of Melchizedek. This signifies that Jesus' priesthood is eternal, not based on lineage but on an indestructible life, making Him the perfect mediator who intercedes for us. Thus, our giving in the Kingdom of God is a testament to the eternal priesthood of Jesus, honoring Him as our provider and priest after the order of Melchizedek.
