Before venturing where darts are flying...

I said, "I will watch my ways
and keep my tongue from sin;
I will put a muzzle on my mouth
while in the presence of the wicked."

Ps 39:1 

Your prayer should be, "Hold thou me up, and I shall be safe."
Having prayed, you must also watch; guarding every thought, word, and action, with holy jealousy. Do not expose yourselves unnecessarily; but if called to exposure, if you are bidden to go where the darts are flying, never venture forth without your shield (faith); for if once the devil finds you without your buckler, he will rejoice that his hour of triumph is come, and will soon make you fall down wounded by his arrows. Though slain you cannot be; wounded you may be. "Be sober; be vigilant, danger may be in an hour when all seemeth securest to thee." Therefore, take heed to thy ways, and watch unto prayer. No man ever fell into error through being too watchful. May the Holy Spirit guide us in all our ways; so shall they always please the Lord. Charles Spurgeon
