David wrote Psalm 86. Verse 11 says, “Teach me Your way, O Lord; I will walk in Your truth; unite my heart to fear Your name.”

For ‘unite’ my margin says give me singleness of heart

Psalm 18:30 says that the way of the Lord is perfect. Psalm 138:8 says, “The Lord will perfect that which concerns me…” 

Lord, I ask You to gather up my straying thoughts, distractions, and anything that would pull away my focus on You. Don’t let anything stop Your way to accomplish my inner transformation 

2 Corinthians 3:18 says, “…with unveiled face, beholding as in a mirror the glory of the Lord, are being transformed into the same image from glory to glory, just as by the Spirit of the Lord.”
