Obedience is something learned. Some of the lessons may take a while and a few tries before we get it. And, as soon as we get it… seems the obedience level goes up a notch or two so we can learn more obedience.
The book of Hebrews says that even Jesus learned obedience through the things, which he suffered. “Although he was a Son, he learned obedience from the things which he suffered.” (Hebrews 5:8) If as The Son he had to learn obedience we surely know as sons and daughters we too will learn obedience through suffering. But we will learn.
The suffering part of this can be many things but to me it is like the proverbial rock with a diamond in the middle: all the outside shell of rock is the suffering required to get to the diamond of obedience.
“Whoever believes in the Son has eternal life; whoever does not obey the Son shall not see life, but the wrath of God remains on him.” Jesus
