This would seem to imply that there are some people who do not have a chance of salvation. We know what God wants. He wants everyone to spend eternity in glory.
(2 Peter 3:9 KJV) The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.Yet here it says that some will not have a “prayer”. What gives?
I can only think that there comes a time in life when we have said “no” to God so many times and made so many selfish decisions that we are not willing or able to repent and change direction. The immediate context is adultery but we know that sexual sin does not automatically put you beyond the reach of God’s grace. Consider David and Bathsheba as an example. The problem is in our hearts and does not develop over night.
So? Walk in obedience. No one moment of weakness or sin will condemn you. Repeated rejection of forgiveness can.
