Not all Scripture is God-breathed. There are verses that also dishonor God. For example, subject of preaching seems to be too illogical even though it is the very basis of many sects [especially of JW organization which defines itself as the preaching organization]. To mention a few reasons why preaching commission is illogical:
1) Preaching commission is followed by all sorts of unreasonable instructions (such as 10:23, 34, 37 …etc. compare Ezekiel 3:18) which would not originate from God or Jesus. It is unlikely that they would say ‘fear should be your motive behind your service to God’ (Mathew 10:28, 33) because what is done out of fear is mechanical and is also as good as nothing being done.
2) In contrast to Mathew 6:2, 3, 5, 16 where he said what is done for reward is useless, it is unlikely that Jesus would say: “Every one therefore who shall confess me before men, him will I also confess before my Father who is in heaven.” (Mathew 10:32) This statement (often used to encourage the preachers to do more) dishonors Jesus and God because it essentially means: ‘If you do this we will do that for you’ which is a worldly attitude against which Jesus himself cautions us in great detail (John chapter 15, 17 … etc) and contradicts other fundamental truths Jesus emphasized earlier such as Mathew 5:44-48.
3) Result-wise too preaching is unnecessary as it accomplishes nothing because everyone already knows what is right and wrong. For example, people are quick to notice the wrong when it is committed by others [which proves they know ‘what is wrong?’] and are quick to seek glory for the good when it is committed by themselves [which proves they know ‘what is right?’]. We all know what actions of others make us happy and unhappy which means we know what actions to be adopted and what actions to be avoided in relation to others. We have also an ocean of experiences (of our own and of others) to decide what is beneficial and harmful.
4) We are already endowed with the capacity to live as though in heaven. When we are fully focused on the now we live as though in heaven [for example, three hours in an examination hall are felt by us like three seconds; in contrast three hours waiting in the Airport when we have something urgent to do on arrival are felt by us like three days]. When we base our happiness on perfect behavior of others we live as though in hell because they cannot often rise to the level of our expectation as actions of others depend on many factors and forces often beyond their control. Even when we are wronged, we have the freedom to move ahead leaving the past where it belongs to and to fully focus on the now which again makes us live as though in heaven. Jesus reiterated this saying: “the kingdom of God is within you.” (Luke 17:21)
[Unfortunately, here too preachers tried to distort the meaning replacing the phrase “within you” with the phrase “in your midst.” But they didn’t know Jesus did mean Kingdom of God is “within” or “inside” us because he used the same Greek word in other unambiguous verses (such as Luke 11:39) where he says: “You Pharisees clean the outside of the cup and dish, but inside you are full of greed and wickedness.” If one wants he can choose to make his life heaven or hell. It’s all within us because our mind is too wonderful that it can choose to be self-contented (like some of the poor people do) or greedy (like some of the rich people do) in any circumstances.]
Thus, the major subject of preaching too falls into the category of God-dishonoring subjects such as those where God is shown as saying ‘I don’t like humans to become like Me’ (Genesis 3:22); ‘I would not permit humans to undertake engineering wonders’ (Genesis 11:4-7); ‘I authorize plundering and killing’ (Numbers 31); ‘Let sinners do the greatest sin of murdering an innocent, the value of which I would use to take away the sins of the world’ (John 1:29); ‘I have predetermined everything that happens’ (Isaiah 40:13; Ephesians 1:3-12; Romans 8:28) ….etc. all of which are obviously the product of human thinking.
