28 Pay careful attention to yourselves and to all the flock, in which the Holy Spirit has made you overseers, to care for the church of God, which he obtained with his own blood.
29 I know that after my departure fierce wolves will come in among you, not sparing the flock;
30 and from among your own selves will arise men speaking twisted things, to draw away the disciples after them.
31 Therefore be alert, remembering that for three years I did not cease night or day to admonish every one with tears.
We are now seeing false teachers arise from among us speaking twisted things and luring so many away. And they also export their twisted teaching worldwide.
Yet some leading overseers in this part of the world even call these people as one of us and standing with them. They are not alert. They have failed to care for the flock of Jesus our Lord which He had obtained by His blood. I pray that these leaders will wake up for because of their respectable standing in Christendom, the flock is not aware of the danger and will follow their decision of affirming the false teachers. Not only have they failed the flock but more importantly their dear Lord whom they claim to serve.
Why did Paul admonish for 3 years with tears ? Because it concerns eternal life and death of those disciples who are lured away ! A true faithful servant will not see fellow servants die a second death. So all the more, the overseers must pay close attention to protect the flock from the wolves, the false teachers.
By speaking against cautious and faithful overseers, who contend against false teaching, on the pretext of unity and peace, the detractors are guilty of trivializing this exhortation of the Word of God in Acts 20:28-31 and participating in their wicked works by affirming them. 2 John 1:10-11.
