"He has shown you, O man, what is good; And what does the Lord require of you But to do justly, To love mercy, And to walk humbly with your God?" -Micah 6:8 (NKJV)
let it go- "get over it!" or "give it to god" or more eloquently - "...grant me the serenity to accept the things I cannot change, The courage to change the things I can, And wisdom to know the difference." If you can do that, life is soooo much better.
If ONLY we study and follow His Word, we are assured that we will arrive at the very best that can ever happen to us.
"For God has not given us a spirit of fear, but of power, and of love, and of a sound mind." 2 Timothy 1:7
