Chasidut su Salmi 6:78

Similarly, we find in the Midrash Sochar Tov: “How may a young man make his path pure? By serving according to Your word” (Tehillim 119), Shlomo said, “In all your ways know Him.” If you know and are conscious of God in all that you do, He will straighten the paths before you. Thus, it is said (Tehillim, 16), “Make the path of life known to me.” So too, Moshe said to God (Shemot, 33), “Now, if I have found favor in your sight, let me know Your ways.” And also (Tehillim, 25), “Lead me in Your truth, and teach me, for You are the God of my salvation.” And (Tehillim, 86), “God, teach me Your way.” And it is written (Yermiyahu, 6), “Stand on the roads and see, and ask about the ways of the world, and see which is the good way. Then walk in it, and find rest for your soul.” Look at the path that Avraham took, and look at the path that Nimrod took, and see who succeeded. So too did David say, “And you, Shlomo my son, know the God of your fathers, and serve him.”

Constancy in divine service is of the essence. However it is impossible for someone to connect to constant service if he does not constantly quest for it. Please note that King David supplicated God (Psalms 86:11), "Show me Your way, O Lord; I will walk in Your truth; let my heart be undivided in reverence for Your name." He had already killed his evil impulse, as the Gemara (Talmud Yerushalmi, Berakhot 9:5) says; and had risen to the highest level of holiness - so much so that he merited to be one of the legs of [God's] throne of glory. Yet in spite of all this, He supplicated God, like someone on the outside and someone who has not started his divine service, "Show me Your way, O Lord; I will walk in Your truth." And he did not only quest for this occasionally and at special times, but rather constantly - as it is written (Psalms 86:3), "for I call out to You the whole day." Picture this: A prince is lost in a mountainous and desolate wilderness among predatory animals and murderous ambushers. But he knows that there is a path there that leads back to his father, the king. However the path is hidden from him and he does not recognize it. How great and constant would be his quest and his search for the path? And how great would be his cries to his father, "Show me your way, O father!" Only if you can see yourself as a lost son of the King that is distanced from the King, your Father in the Heavens - lost in the desolation of this world, physicality and stupidities that injure the body and kill the spirit - only then will you constantly quest for God's path and constantly cry out, "Show me Your way, O Lord!" And to the extent that you are constant about questing, you will be constant in your divine service. But if you are not constant in supplicating from the bottom of your heart, it will also be impossible for you to serve Him with constancy.
