Isaiah 40:30–31
30 Even youths shall faint and be weary,
and young men shall fall exhausted;
31 but lthey who wait for the Lord shall renew their strength;
they shall mount up with wings mlike eagles;
they shall run and not be weary;
they shall walk and not faint.
Romans 12:2
2 cDo not be conformed to this world,1 but be transformed by dthe renewal of your mind, that by testing you may ediscern what is the will of God, what is good and acceptable and perfect.2
