Q85. How do I go about worshipping Him with my spirit and heart?
You must first come to a genuine knowledge of Him. David said to his son, "Know the God of your father, Solomon, and serve Him with a whole heart". Notice the order: he first says know Him, and then serve Him with a whole heart.

1 Chronicles 28:9
“And thou, Solomon my son, know thou the God of thy father, and serve him with a perfect heart and with a willing mind: for the LORD searcheth all hearts, and understandeth all the imaginations of the thoughts: if thou seek him, he will be found of thee; but if thou forsake him, he will cast thee off for ever.”
