"... dies without mercy..." Heb 10:28
"... died in faith..." Heb 11:13
Let's apply these to salvation:
My friend, take your pick. Either you die without the mercy of God, expressed on the cross of Calvary when Christ died for you, applied to you or you die trusting in it.
The former is dying without mercy. The latter is dying in faith. The former is to "die in your sins" (John 8:24). The latter is to die forgiven and saved.
Why don't you receive His mercy, His salvation and His forgiveness by putting your trust in Christ and what He did on the cross for you? So that when the curtain falls on your life you will die not without mercy but die the death of the forgiven.
