There are many excellent Religious Teachers with good appearances and eloquence, but wouldn't major on the reality of the Cross: the life of Jesus. Because they wouldn't want to OFFEND their people or followers, and LOSE their members thereby.

There is ONLY ONE WAY that leads to life, which is the NARROW WAY which Jesus and his apostles did preach. But when the Preacher's MIND is on Money and Popularity: to gather great Crowd and have a great name in the world, then COMPROMISE and LIES would be certain. He would definitely have to BOW the knee and hold hands with the devil to become GREAT by WATERING DOWN his message to sooth his hearers by mixing psychology with the gospel, and saying NICE things to stir their emotions and attention.

Jesus couldn't care less for people's Money, Opinions or appearing COOL and acceptable to them. And when MANY of his followers got offended with what he preached, he just LET THEM GO:

John 6:66 KJV
From that time MANY of his disciples WENT BACK, and walked NO MORE with him.

Then he faced his remaining TWELVE disciples:

John 6:67 KJV
Then said Jesus unto the twelve, Will ye also GO AWAY?

Although, those WORDS were really strong, but these were NOT willing to WALK AWAY:

John 6:68 KJV
Then Simon Peter answered him, Lord, to WHOM SHALL WE GO? thou hast the WORDS OF ETERNAL LIFE.

Yet, among the few was the devil:

John 6:70 KJV
Jesus answered them, Have not I chosen you TWELVE, and one of you is a DEVIL? (Judas)

We must be sure to count the COST of Eternal life first to avoid just PLAYING Church and Religion, and living in a great Self/Church Deception.

Moreover, we shouldn't be teachers or preachers if we're not willing to TOTALLY COMMIT to the truth. It's better to forget Lord's work, and rather go and do some BUSINESS than fooling oneself and people. And especially TO AVOID GREATER judgement on oneself:

Jas.3.1 - My brethren, let NOT MANY of you BECOME teachers, knowing that we shall receive a STRICTER JUDGMENT.

Again we must be SURE to count the cost to enter God's kingdom:

Matthew 7:14-15 KJV
Because strait is the gate, and NARROW is the way, which leadeth unto life, and FEW there be that FIND IT.

[15] Beware of FALSE PROPHETS (or Preachers who Broaden it to become GREAT!), which come to you in SHEEP'S CLOTHING (it means they use CORRECT doctrines and others), but INWARDLY they are ravening WOLVES (to BITE your Money and Attention).

May the Lord Jesus bless you.

2 Timothy 4:3 KJV
For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears;
