philippians 4:8

So...until then...I will do my best to think on the true and noble and right. I will set my thoughts on whatever is pure and lovely and admirable. If something is excellent or praiseworthy...I will think on those things. And if my thoughts are on none of those things? I will pray...and ask God to help me set my mind on whatever is good...whatever is of Him....and to let those other thoughts go. Because if it is not of Him...it is of no use to me.
