When did we become “God”

The Great Commission
16Now the eleven disciples went to Galilee, to the mountain to which Jesus had directed them. 17And when they saw him they worshiped him, but some doubted. 18And Jesus came and said to them, "All authority in heaven and on earth has been given to me. 19 Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age."

The great commission, something that as Christians we learn early in our newly found walk and way, but for many it seems to have been forgotten for a more “glamorous” or “Christian” seeming life. I sit here day by day and listen to people discuss how this preacher is wrong and how that pastor is not a “true” Christian. But we see here in the Great Commission that us judging others is never part of the command. Have we not noticed that Jesus says in verse 18 “All authority in heaven and on earth has been given to me.” I’m pretty sure that when Jesus said “ALL” and “Heaven and Earth” He meant it. This means that He alone has the authority to judge ones eternity or life, not us.
As I read on the phrase in verse 20 “teaching them to observe” caught my eye. So I went to my trusty research tool www.blueletterbible.org and look up the verse. Then I looked up the Strong’s number for that phrase, which pulled up “τηρέω” which means
1) To attend to carefully, take care of
a) To guard
b) metaph. to keep, one in the state in which he is
c) To observe
d) To reserve: to undergo something
So if we take this definition then it is our job to teach people to take care of, to guard, to attend to carefully all the things that Jesus has commanded us. So with that said, to go back to my previous statement of how I am constantly hearing Christians criticize preachers and pastors saying that their eternity is unsure because of what they are saying. Know that Jesus has all authority in heaven and in earth, what does JESUS say about us judging others.
Judging Others (Matthew 7)
1"Do not judge, or you too will be judged. 2For in the same way you judge others, you will be judged, and with the measure you use, it will be measured to you.
3"Why do you look at the speck of sawdust in your brother's eye and pay no attention to the plank in your own eye? 4How can you say to your brother, 'Let me take the speck out of your eye,' when all the time there is a plank in your own eye? 5You hypocrite, first take the plank out of your own eye, and then you will see clearly to remove the speck from your brother's eye.
6"Do not give dogs what is sacred; do not throw your pearls to pigs. If you do, they may trample them under their feet, and then turn and tear you to pieces.
Judging Others (Luke 6:37)
37"Do not judge, and you will not be judged. Do not condemn, and you will not be condemned. Forgive, and you will be forgiven. 38Give, and it will be given to you. A good measure, pressed down, shaken together and running over, will be poured into your lap. For with the measure you use, it will be measured to you."
So when did we become “God” and take on the authority to sit around and judge others as the Pharisees did. To sit around and say that this preacher is not saved because he does not believe what I believe. Or to discuss with like minded brethren about how this pastor is a hieratic for living out his Christian walk in a way that doesn’t suit me. When did we take the authority away from Jesus and what he did on the cross. Instead of judging and saying that this person has their theology all wrong and that the result of that faulty theology will be them missing heaven. How about we pray and ask God to help all of us better understand his word. We walk around arrogantly thinking that we fully understand what God’s word says and how it applies to our walk with the Lord today. We are human and our thinking is corrupted as our flesh is. So what makes us think that in our corrupted state of being we can truly say, “My theology is spot on, and any other is a fallacy.”
I say we just realize that we are human and will never fully, completely understand the living word of God. And that we must daily ask God for guidance and help comprehending when we read. So I ask again When did we become “God” and take the authority away from Jesus and what he did on the cross?
