You Only Live Once, and it lasts forever. Wait, what?
Yes, your everlasting life or everlasting death have already begun. You see, life and death have nothing to do with the body. Life is eternity with God, Death is eternity without God.
It is not coincidence that the point of Adam's obedience in the Garden was the Tree of the Knowledge of Good and Evil. That tree was Adam's tithe; his point of obedience.
We call it tithe, an Old English word meaning one tenth, from Abram's giving "tithes of all" to Melchizadek after the battle of the kings. Leviticus prescribes tithing to the Temple for the children of Israel. So we see tithing has both an amount and a purpose. It is a matter of obedience. Your obedience then gives God license to work in your life.
God needs a license to work in my life, you ask? Yes. He must have your cooperation. You have a free will. You choose life or death (Deut. 30:15-20). Jesus tells us to render unto Caesar that which is Caesar's and unto God that which is God's (Matt. 22:21).
With every choice we make we are choosing life or death, blessing or cursing. Every decision we make on earth is an indication of whether we will follow God or not; whether we will be obedient. The choice is yours. You choose who you serve, Life or Death. They are both everlasting.
