God is Merciful

The following discussion by Ammon on God's mercy sticks out to me and impresses me:

17 Who could have supposed that our God would have been so merciful as to have snatched us from our awful, sinful, and polluted state?
18 Behold, we went forth even in wrath, with mighty threatenings to destroy his church.
19 Oh then, why did he not consign us to an awful destruction, yea, why did he not let the sword of his justice fall upon us, and doom us to eternal despair?
20 Oh, my soul, almost as it were, fleeth at the thought. Behold, he did not exercise his justice upon us, but in his great mercy hath brought us over that everlasting gulf of death and misery, even to the salvation of our souls (Alma 26).

The phrase that impresses me most is in bold: it is that God withheld exercising the full measure of justice in regard to these vile sinners. It makes me realize that if God punished all sin immediately then I would imagine that the sons of Mosiah would have been justly destroyed for their many sins long before their repentance and long before their missionary labors, and long before the conversion of all these thousands of Lamanites. God saw their end from the beginning. He is so wise. He is all-wise. This event depicted here should lead me to trust Him more fully; trust in His wisdom and timing always. 

God's mercy has been demonstrated in my own life so many times. Indeed in my own history their were long stretches of time when God withheld justice from coming down and crushing me. I, like Ammon, should always remember this and rejoice that God is merciful.
