Wolves and Grace

Acts 20:29-32 
29 For I know this, that after my departure savage wolves will come in among you, not sparing the flock. 30 Also from among yourselves men will rise up, speaking perverse things, to draw away the disciples after themselves. 31 Therefore watch, and remember that for three years I did not cease to warn everyone night and day with tears. 32 “So now, brethren, I commend you to God and to the word of His grace, which is able to build you up and give you an inheritance among all those who are sanctified.

There are always wolves pretending to be sheep among the flock.  They do not relent.  There are also those within who twist God's word to pull people away from truth, just to make followers of themselves, twice the sons of hell as themselves.  This is why we watch, pray, and put the sheep in the sure hands of the eternal Shepherd and His word.  God's words of life build up and remind of the inheritance by grace through faith for those who are set apart to Him.  Watch, pray, and preach the word. That is our defense.
