Some people may feel that when it comes to the scriptures that a teacher is not needed, and that they can learn on their own. This couldn't be further from the truth. An example of this is given in the book of Acts when Philip was led by the spirit to speak to an Israelite man from Ethiopia, who had been scattered to that country since the time of the Greeks, even to today (Zechariah 7:14, Tobit 13:3, James 1:1).
Acts 8:29-31  Then the Spirit said unto Philip, Go near, and join thyself to this chariot.  And Philip ran thither to him, and heard him read the prophet Esaias, and said, Understandest thou what thou readest?  And he said, How can I, except some man should guide me? And he desired Philip that he would come up and sit with him.
The Most High set up teachers in Israel to instruct the people in righteousness.
Acts 13:1 ¶ Now there were in the church that was at Antioch certain prophets and teachers; as Barnabas, and Simeon that was called Niger, and Lucius of Cyrene, and Manaen, which had been brought up with Herod the tetrarch, and Saul.
Jeremiah 3:15 And I will give you pastors according to mine heart, which shall feed you with knowledge and understanding.
Without a proper teacher or guide we are doomed to follow our own will and way of doing things, which is not the way we are to conduct ourselves according to scripture.
Sirach 5:2 Follow not thine own mind and thy strength, to walk in the ways of thy heart:
Jeremiah 17:9 The heart is deceitful above all things, and desperately wicked: who can know it?
We cannot be willful if we desire to have knowledge and wisdom. We must submit ourselves to the word of the Most High. As we look at the world around us within all walks of life, a guide, mentor, instructor, trainer, or a teacher of some sort is necessary, especially when it comes to understanding the scriptures. Because of the complexity of the biblical scriptures it is of the utmost importance that a well learned experienced teacher instruct you in order to avoid a wrong understanding and misinformation.
1Timothy 3:6 Not a novice, lest being lifted up with pride he fall into the condemnation of the devil.
Isaiah 29:12 And the book is delivered to him that is not learned, saying, Read this, I pray thee: and he saith, I am not learned.
A true teacher of the Most High can clearly show the truth and understanding of the scriptures. He is able to show us how things ought to be done, what it is we are doing wrong or may be doing right. When we are born into this world do we not have parents that teach us how things are to be done? Teachers are very necessary.
We also had teachers throughout our formal education (elementary, middle school, high school etc.).
Q. What if I don’t like being told what to do?
A. The scriptures teach us that you must learn to submit to order and instruction, unless what you are being told or asked to do goes against the laws of the Most High.
Psalms 2:10 ¶ Be wise now therefore, O ye kings: be instructed, ye judges of the earth.
Hebrews 13:17 Obey them that have the rule over you, and submit yourselves: for they watch for your souls, as they that must give account, that they may do it with joy, and not with grief: for that is unprofitable for you.
You must submit yourself (obey) to your elders and those who are in the position of authority or leadership within the congregation, else how would one increase his learning and grow spiritually? How can you build a nation if everyone wants to follow their own mind and way? (1 Corinthians 14:26, 33, 40) It is the elder's and leader's duty to keep order, teach the people, and protect the people as a shepherd, overseer, leader etc. (John 10:11, Titus 1:7, Malachi 2:7)
Sirach 10:1 A wise judge will instruct his people; and the government of a prudent man is well ordered.
Examine your sports field, no matter how well NBA, or NFL players may play or how old they may become, they still have a coach.
Even on your job, you have a manager, supervisor, or boss of some degree to make sure you are doing what you need to be doing decently and in order.
We must apply these same concepts with our spiritual development and growth as well. But just as the Israelite man from Ethiopia we must desire to be instructed and taught.
Sirach 6:32 My son, if thou wilt, thou shalt be taught: and if thou wilt apply thy mind, thou shalt be prudent.
Job 6:24 Teach me, and I will hold my tongue: and cause me to understand wherein I have erred.
Sir. 6:36 And if thou seest a man of understanding, get thee betimes unto him, and let thy foot wear the steps of his door.
The only sure way to avoid confusion is to seek out adequate teachers of the Most High that hold his word in sincerity and truth. This can only be done when you have someone there showing you the way you must walk.
Job 34:32 That which I see not teach thou me: if I have done iniquity, I will do no more.
Q.What if I don’t trust the teacher? What if he leads me in the wrong direction?
A.Remember, you have to try the spirits by the spirits and use the word of God as the filter. (1 John 4:1, John 14:17, Psalms 119:142).
Ecclesiastes 12:9 And moreover, because the preacher was wise, he still taught the people knowledge; yea, he gave good heed, and sought out, and set in order many proverbs.
2 Timothy 2:15 Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.
Q.What if I don’t like being around other people?
A.We are commanded to gather and fellowship with one another or else, how would you build a nation? We have to put our feelings and previous experiences aside and submit ourselves to the will of the Most High.
Hebrews 10:25 Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching.
