To receive the optimum God-kind of abundance, you must not overlook or under-emphasize the basic building blocks of your biblical abundance plan. To open heaven's windows and keep them open, you must tithe. Biblically, tithing is not optional. You owe God the tithe.

God says when we don't tithe, we rob Him. We tithe at His command, not our discretion. By faithfully bringing Him the tithe, we establish our honesty and obedience.

In Hebrews 7:1-10 we see that Abraham paid tithes. In fact, Abraham tithed for all posterity—for his natural children (seed), and for the spiritual children (seed) who now live in the dispensation of grace: "And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise" (Gal. 3:29).

The obligation of tithing reaches across the pre-law dispensations, the dispensation of the law, and now into the post-law dispensation of grace.

Remember: Faithful tithing opens the windows of heaven, making this basic giving (the tithe) vital. Without the windows of heaven open, nothing can flow from God to you or me.
