Acts 20:28 ESV
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.
Proverbs 4:23 NIV
23 Above all else, guard your heart,
for everything you do flows from it.
Acts 20:29-38 ESV
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. 32 And now I commend you to God and to the word of his grace, which is able to build you up and to give you the inheritance among all those who are sanctified. 33 I coveted no one's silver or gold or apparel. 34 You yourselves know that these hands ministered to my necessities and to those who were with me. 35 In all things I have shown you that by working hard in this way we must help the weak and remember the words of the Lord Jesus, how he himself said, ‘It is more blessed to give than to receive.’”
36 And when he had said these things, he knelt down and prayed with them all. 37 And there was much weeping on the part of all; they embraced Paul and kissed him, 38 being sorrowful most of all because of the word he had spoken, that they would not see his face again. And they accompanied him to the ship.
John 10:14 NIV
14 “I am the good shepherd; I know my sheep and my sheep know me—
1 Timothy 4:15-16 NIV
15 Be diligent in these matters; give yourself wholly to them, so that everyone may see your progress. 16 Watch your life and doctrine closely. Persevere in them, because if you do, you will save both yourself and your hearers.
Matthew 7:15 NIV
15 “Watch out for false prophets. They come to you in sheep’s clothing, but inwardly they are ferocious wolves.
1 John 2:22-23 NIV
22 Who is the liar? It is whoever denies that Jesus is the Christ. Such a person is the antichrist—denying the Father and the Son. 23 No one who denies the Son has the Father; whoever acknowledges the Son has the Father also.
2 Corinthians 11:12-15 NIV
12 And I will keep on doing what I am doing in order to cut the ground from under those who want an opportunity to be considered equal with us in the things they boast about. 13 For such people are false apostles, deceitful workers, masquerading as apostles of Christ. 14 And no wonder, for Satan himself masquerades as an angel of light. 15 It is not surprising, then, if his servants also masquerade as servants of righteousness. Their end will be what their actions deserve.
Matthew 7:16a NIV
16 By their fruit you will recognize them.
Jeremiah 17:5-7 NIV
5 This is what the Lord says:
“Cursed is the one who trusts in man,
who draws strength from mere flesh
and whose heart turns away from the Lord.
6 That person will be like a bush in the wastelands;
they will not see prosperity when it comes.
They will dwell in the parched places of the desert,
in a salt land where no one lives.
7 “But blessed is the one who trusts in the Lord,
whose confidence is in him.
8 They will be like a tree planted by the water
that sends out its roots by the stream.
It does not fear when heat comes;
its leaves are always green.
It has no worries in a year of drought
and never fails to bear fruit.”
Jude 11 NIV
11 Woe to them! They have taken the way of Cain; they have rushed for profit into Balaam’s error; they have been destroyed in Korah’s rebellion.
Matthew 23:1-4 NIV
Then Jesus said to the crowds and to his disciples: 2 “The teachers of the law and the Pharisees sit in Moses’ seat. 3 So you must be careful to do everything they tell you. But do not do what they do, for they do not practice what they preach. 4 They tie up heavy, cumbersome loads and put them on other people’s shoulders, but they themselves are not willing to lift a finger to move them.
