Proverbs 4:25 Let your eyes look straight ahead; fix your gaze directly before you.
How many times have you been told to keep your eyes to yourself or keep them away from stuff?
The more we allow ourselves to see and watch things, the more we are willing to accept those things into our lives.
If you want to achieve a certain goal in life, then keeping your eyes firmly fixed on that goal will make it more likely to happen.
God wants you to look to Him in all things so your life will be centred around Him.
