Romans 12:1 Therefore I urge you, brothers and sisters, by the mercies of God, to present your bodies [dedicating all of yourselves, set apart] as a living sacrifice, holy and well-pleasing to God, which is your rational (logical, intelligent) act of worship.
The Word directs us that our lives are the very act of sacrifice that He is looking for. Not just our money, or are time, or are occupation. He is looking for us to give him everything that we are. Many see giving as the churches get rich scheme and fail to miss the true intention of the Father's desire for us to give money. The Father doesn't need our money, He's looking for our obedience. When we honor Him with our "want to" desire, he is given an open season for blessings on our life. We are always looking up for an open heaven!
