A meeting according to wikipedia definition is a gathering of two or more people that has been convened for the purpose of achieving a common goal through verbal interaction, such as sharing information or reaching agreement.
Mt 18:20 For where two or three are assembled in my name, there am I in the midst of them.
The purpose of Jesus Christ being in the midst of two or more people is to act as mediator between God and men. He should not be there, in the first place, doing nothing.
1 Tim 2:5 For there is one God, and one mediator between God and men, the man Christ Jesus;
Meetings may occur face to face or virtually, as mediated by communications technology, such as a telephone conference call, a skyped conference call or a videoconference.
Between God and men, the meeting is face to face and personal. And God said "I will go also".
Zech 8:20 Thus saith the LORD of hosts: It shall yet come to pass, that there shall come people, and the inhabitants of many cities:
Zech 8:21 And the inhabitants of one city shall go to another, saying, Let us go speedily to pray before the LORD, and to seek the LORD of hosts: I will go also.
Thus, a meeting may be distinguished from other gatherings, such as a chance encounter (not convened), a sports game or a concert (verbal interaction is incidental), a party or the company of friends (no common goal is to be achieved) and a demonstration (whose common goal is achieved mainly through the number of demonstrators present, not verbal interaction).
The meeting of God and Satan is a good example of a chance encounter.
Job 2:1 Again there was a day when the sons of God came to present themselves before the LORD, and Satan came also among them to present himself before the LORD.
Job 2:2 And the LORD said to Satan, Whence comest thou? and Satan answered the LORD, and said, From going to and fro on the earth, and from walking up and down upon it.
Job 2:3 And the LORD said to Satan, Hast thou considered my servant Job, that there is none like him on the earth, a perfect and an upright man, one that feareth God, and shunneth evil? and still he holdeth fast his integrity, although thou movedst me against him, to destroy him without cause.
Meetings and gatherings are done for the purpose of seeking grace or favor and mercy from the Lord. The presence of God and Jesus Christ is a prerequisite in resolving the noble issues that may be bestowed upon us.
2 Chron 7:14 If my people, who are called by my name, shall humble themselves, and pray, and seek my face, and turn from their wicked ways; then will I hear from heaven, and will forgive their sin, and will heal their land.
