Notice the reference made in Matthew 10 is written alongside elements of prophecy that are seen in Matt 24.

Mat 10:17-23 But beware of men: for they will deliver you up to the councils, and they will scourge you in their synagogues; (18) And ye shall be brought before governors and kings for my sake, for a testimony against them and the Gentiles. (19) But when they deliver you up, take no thought how or what ye shall speak: for it shall be given you in that same hour what ye shall speak. (20) For it is not ye that speak, but the Spirit of your Father which speaketh in you. (21) And the brother shall deliver up the brother to death, and the father the child: and the children shall rise up against their parents, and cause them to be put to death. (22) And ye shall be hated of all men for my name's sake: but he that endureth to the end shall be saved. (23) But when they persecute you in this city, flee ye into another: for verily I say unto you, Ye shall not have gone over the cities of Israel, till the Son of man be come.

Mat 24:9-14 Then shall they deliver you up to be afflicted, and shall kill you: and ye shall be hated of all nations for my name's sake. (10) And then shall many be offended, and shall betray one another, and shall hate one another. (11) And many false prophets shall rise, and shall deceive many. (12) And because iniquity shall abound, the love of many shall wax cold. (13) But he that shall endure unto the end, the same shall be saved. (14) And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.

Luke 21 as well as Mark 13 corresponds to the Olivet Discourse in Matt 24. In Luke and mark, the same notes found in both Matt 10 and Matt 24 are found.

Luk 21:12-18 But before all these, they shall lay their hands on you, and persecute you, delivering you up to the synagogues, and into prisons, being brought before kings and rulers for my name's sake. (13) And it shall turn to you for a testimony. (14) Settle it therefore in your hearts, not to meditate before what ye shall answer: (15) For I will give you a mouth and wisdom, which all your adversaries shall not be able to gainsay nor resist. (16) And ye shall be betrayed both by parents, and brethren, and kinsfolks, and friends; and some of you shall they cause to be put to death. (17) And ye shall be hated of all men for my name's sake. (18) But there shall not an hair of your head perish.

Mar 13:9-13 But take heed to yourselves: for they shall deliver you up to councils; and in the synagogues ye shall be beaten: and ye shall be brought before rulers and kings for my sake, for a testimony against them. (10) And the gospel must first be published among all nations. (11) But when they shall lead you, and deliver you up, take no thought beforehand what ye shall speak, neither do ye premeditate: but whatsoever shall be given you in that hour, that speak ye: for it is not ye that speak, but the Holy Ghost. (12) Now the brother shall betray the brother to death, and the father the son; and children shall rise up against their parents, and shall cause them to be put to death. (13) And ye shall be hated of all men for my name's sake: but he that shall endure unto the end, the same shall be saved.

Since Matt 10 involves the same elements as Matt 24 and Luke 21, and all three note the coming of the Lord, whatever the coming was in 24 it is the coming in Matt 10.

And Col. 1:5-6, 23 speak of the gospel having gone to ALL THE WORLD by the time Col was written.

Col 1:5-6 For the hope which is laid up for you in heaven, whereof ye heard before in the word of the truth of the gospel; (6) Which is come unto you, as it is in all the world; and bringeth forth fruit, as it doth also in you, since the day ye heard of it, and knew the grace of God in truth:

Col 1:23 If ye continue in the faith grounded and settled, and be not moved away from the hope of the gospel, which ye have heard, and which was preached to every creature which is under heaven; whereof I Paul am made a minister;

As Jeffrey said, Colossians was written after Pentecost.

Matt 21:40 shows the sort of coming these instances are about:

Mat 21:40 When the lord therefore of the vineyard cometh, what will he do unto those husbandmen?
