We were lost! We were dead in sin! No way to be in God's presence. And the verdict was in -- our sentence was separation from God, death, and hell. Our rightful punishment for what we've done.
Floodgate? Jesus denied himself all that it is to be God by coming down in human form, living a life of poverty in an age before indoor plumbing, electricity, and the ability to control temperatures inside to comfortable levels. He lived in a time when his people had become unwilling slaves to a mighty empire. He grew up in that. And then he taught all about God, until he was beaten, whipped, taunted, and nailed to wood all out of scorn for who he is. He died that way. They even stabbed him after he was dead to make sure he was dead! And he did that to make a way to redeem those his Father gives him, so we can be in God's presence, live, and be with him forever, despite deserving the verdict already received.
Floodgates? Can it be more opened than that? If you're tithing to get something out of God, you're really missing the whole concept of tithing!
