Completeness of Worship

There is another concept used by both the Ramchal and the Chazon Ish in describing the goal of how one must properly serve Hashem. This is called, שלמות העבודה, “a completeness of worship.”
The Ramchal in Messilat Yesharim is more general in terms of explaining this idea. He simply speaks of diligently observing the positive and negative commandments of the Torah.
The Chazon Ish is more specific and detailed in how one achieves this completeness in his serving G-d. He would begin by explaining the necessity of acquiring true Yirat Shamayim, fear of Heaven. One needs to be clear of his place in the world as compared to that of our Creator. Every action is based on his Yirat Shamayim, that will guide him in making the right decisions.
Character building is another essential ingredient in completing a person. He must work on improving his character traits. He needs to overcome such things as anger, jealousy, and arrogance. This takes a serious effort at self improvement.
He must recognize the importance of daily Torah study in depth. One should strive for the level where he can delve into the study of Talmud, as a truth seeking vehicle.
He must be convinced that the Halacha represents absolute Divine truth. There is no truth like this truth.
And the final point on the list of the Chazon Ish is the meticulousness of how one practices Judaism. This is called, דקדוק הדין, where one makes a concerted effort to follow the Halacha in all of its details.
These are levels of observance that require due diligence and sincerity. The reward for these efforts are immeasurable. An individual that has mastered these areas will be shielded by Divine love. His life will be fulfilled with contentment and peace of mind. This is what the Ramchal and the Chazon Ish were trying to teach us. It would be great for us if we would follow their lead.
