Notice how much there is in verse four:
When he asked God to “show him” he was literally asking God to make Himself known to him. If we want to know God like David wanted to know God, it is necessary to begin with repentance and forgiveness. The gift of salvation is the first step in our knowledge of God. As our knowledge of Christ grows, we will begin to understand the meaning of salvation, we will become more knowledgeable about God’s love, mercy and grace.
Then he continued “teach me” Your paths. If we have repented, we will want God to show us the path that He wants us to take and follow Him wherever it leads. Jesus said, “I am the way.” He is not a way, but is the way and is always willing to teach us His way but we must be willing to listen to Him speak to us.
Finally he said, “Lead me in Your truth.” He realized that he was fallible - prone to making the wrong choices. So, he was willing to admit that He needed God’s wisdom in place of his knowledge and that he needed His insights. He willingly begged God to equip him for the life that God had planned for Him.
The verses in psalm 27 tells us of David’s heart and longing for God:
Psa 27:4 One thing have I desired of the LORD, that will I seek after; that I may dwell in the house of the LORD all the days of my life, to behold the beauty of the LORD, and to enquire in his temple.
Psa 27:5 For in the time of trouble he shall hide me in his pavilion: in the secret of his tabernacle shall he hide me; he shall set me up upon a rock.
Psa 27:6 And now shall mine head be lifted up above mine enemies round about me: therefore will I offer in his tabernacle sacrifices of joy; I will sing, yea, I will sing praises unto the LORD.
Psa 27:7 Hear, O LORD, when I cry with my voice: have mercy also upon me, and answer me.
Psa 27:8 When thou saidst, Seek ye my face; my heart said unto thee, Thy face, LORD, will I seek.
It’s my hearts-desire to be like David.
