This book of the law shall not depart out of thy mouth; but thou shalt meditate therein day and night, that thou mayest observe to do according to all that is written therein: for then thou shalt make thy way prosperous, and then thou shalt have good success. – Joshua 1:8
Breathing.
Your heart beat.
The rotation of the Earth around the sun.
Sunlight.
Learning.
Love.
Prayer.
Rejoicing in the Lord always.
Meditating on the Word day and night.
