Take your eyes off things that have no eternal value. God will preserve your life according to His word. Psalm 119.37. Our life is dependent on His word that gives us health to our mortal body.
Joshua was busy planning and seeking God what he should do next when Moses died. At this time of transition, the Lord visited him with a strong mandate to meditate on His word to strengthen his inner man and to have more wisdom. Psalm 119:99.
God be praised!
Prayer: Lord, preserve my life according to your Word as I meditate on Your statutes all day long.
