Father, herein is my prayer, for my eyes be single on You and You alone. Let me not turn to left or right but look straight into your face, which is your presence. Father help me to look to you in all things, guide me in me all my doing. Let Your will be done, the perfect and good will. Thank you Jesus.
Fix our eyes only on Him, the source of light.
Why is the singleness so important?
Verse 24, "No-one can serve two masters. Either he will hate one and love the other, or he will be devoted to the one and despise the other. You cannot not serve both God and Money." Verse 25, "Therefore I tell you, do not worry about your life," The word 'worry' in Greek has it root in the word 'μέριμνα' 'merimna' which means care,anxiety, has its root in the word 'μερίζω' 'merizō' which means to divideto separate into parts, cut into pieces.
Now track back, a divided mind leads to care, anxiety and that leads to worry. So Jesus is saying keep your eyes single, not divided.
People usually say "take care" when they shake hands and part ways. I say don't say that. Rather say "don't care" which means don't be divided. Be single minded. Seek only that which is important. Seek the Light, Life. Seek Jesus.
