“For if we deliberately sin after receiving the knowledge of the truth, there no longer remains a sacrifice for sins, but a terrifying expectation of judgment and the fury of a fire about to consume the adversaries.
For yet in a very little while, the Coming One will come and not delay. But My righteous one will live by faith; and if he draws back, I have no pleasure in him. But we are not those who draw back and are destroyed, but those who have faith and obtain life.”
Hebrews 10:26-27, 37-39 HCSB
This is a recurring theme in Hebrews. I think of it as a warning against “Fire Insurance” – meaning the thinking that OK, I believe in Jesus, I have called on His name. I am saved, so now I can just go right back and be like nothing has changed – NOT true! I am a child of God, I need to act like a son of God (not to be confused with THE Son of God, mind you). My take away is, am I deliberately sinning? Am I doing things and thinking – it’s OK – I am saved! I just have to ask for forgiveness. This isn’t to say that I can never sin again, but there is a big difference between doing something I know is wrong and continuing to do it because I think that I can just go to the bottomless well of God’s mercy and forgiveness and messing up, asking for (and receiving) forgiveness.
