James: 1
12 Blessed is a man who perseveres under trial; for once he has been approved, he will receive the crown of life which the Lord has promised to those who love Him.
Search the New Testament. There is no promise made to anyone who remains under the Law. The only promises in the NT are to those who accept Jesus as Lord and Savior.
And it’s true too that when saved we will begin to “work it out” with “fear and trembling” — because “God works in [us]”.
This is not a selfish fear and trembling. Oh, if I don’t do enough or frequently enough I’ll go to hell forever. An outcome not possible now. But it’s the fear and trembling of everlasting citizens of heaven. Awe might be a better way to put it. One begins to behold the mighty works of God in one’s life. They vary like fireworks vary. Is your life a colored smoke bomb? A little firecracker? A sparkler? Or a dazzling sky shell with an impressive boom?
