Another issue, related to not putting off your salvation experience. Aside from the fact that we don’t know when we will croak, I think that the older one gets, the harder their hearts get, and the less chance they have of repenting. Never impossible, just less likely. Your thoughts.
Pharaoh hardened his own heart against the word from God beyond repentance (Ex. 5:1,2), so God hardened his heart further (Ex. 7:13-14).
From experience, I believe this is a reality today of having lost the ability to grieve unto repentance (2 Cor. 7:10); from God's Word that it will be so even after the removal of the people of Christ (Rev. 9:20,21; 16:21); and also throughout the thousand year reign of Christ (Is. 65:20), until the last judgment..
What do your observations indicate?
Hearts?
For me it's my HEAD!
(Or maybe it's gotten softer...)
