I Samuel 17: 46-47
Said David to Goliath:
"This day the Lord will deliver you into my hands, and I will strike you down and remove your head from you. And I will give the dead bodies of the army of the Philistines this day to the birds of the sky and the wild beasts of the Earth, that all the Earth may know that there is a God in Israel.
"And that all this assembly may know that the Lord does not deliver by sword or by spear; for the battle is the Lord's and He will give you into our hands."
This is David's good beginning. I don't know if he was speaking through his fear, but I can see that fear did not control him. His faith in God caused him to trust God to take control of this battle, as He had promised to do on numerous other occasions when Israel came into this Promised Land.
And David continued to trust God, and tried to always do what God would have him do, even if it was not what he wanted to do.
That's why God said that David was a man after His own heart (I Sam 13:14).
O my Father, I know that David was not perfect, but he did take counsel when what he wanted to do was not right. Help me always to humble myself before You and seek counsel to know what would be right to do before You. Help me always to seek You and Your ways in all my choices and decisions. Help me to continually seek Your ways in my days, and do what pleases You.
May I trust You implicitly, as David did here. May Your Love for me cast out all fear that would try to dissuade me from following Your ways, in not doing what You want me to do; or doing what would be contrary to Your ways and goodness.
And I will never be shaken, even when this whole Earth is shaking under Your wrath and judgment, I will stand firm on Your Word, Your Promises to me.
Even so, come, Lord Jesus!
