Well, is it true? Is that what you believe? That you have to live a defeated, half-hearted christianity until you die? Is that what the kingdom of God is all about? Is that why Jesus came, to sorta, kinda, maybe deliver us?
In the immortal words of Paul: No way! (my translation of μὴ γένοιτο)
Life in Christ is more than that! (Note the in Christ part of that!)
