1 Corinthians 4:9-13
9 For I think that God hath set forth us the apostles last, as it were appointed to death: for we are made a spectacle unto the world, and to angels, and to men.
10 We are fools for Christ's sake, but ye are wise in Christ; we are weak, but ye are strong; ye are honourable, but we are despised.
11 Even unto this present hour we both hunger, and thirst, and are naked, and are buffeted, and have no certain dwelling place;
12 And labour, working with our own hands: being reviled, we bless; being persecuted, we suffer it:
13 Being defamed, we intreat: we are made as the filth of the world, and are the offscouring of all things unto this day.
Jude 17
17 But, beloved, remember ye the words which were spoken before of the apostles of our Lord Jesus Christ;
Acts 2:43
43 And fear came upon every soul: and many wonders and signs were done by the apostles.
Acts 5:12
12 And by the hands of the apostles were many signs and wonders wrought among the people; (and they were all with one accord in Solomon's porch.
Acts 1:21-22
21 Wherefore of these men which have companied with us all the time that the Lord Jesus went in and out among us,
22Beginning from the baptism of John, unto that same day that he was taken up from us,"must one be ordained" to be a witness with us of His resurrection.
1 Corinthians 15:8
8 And last of all He (Christ) was seen of me also, as of one born out of due time.
The true apostles of Jesus Christ were chosen of God .. and not by men. They laid the foundation for Christ's church at the cost of their own lives. Paul was the last, as one born out of due time of that specific generational period ... the apostolic age. There were some appointed by the apostles to assist in their work .. but this too took place during that same generational apostolic period. Of the many great men of God to follow throughout church history following the completion of canon, none laid claim to being an apostle.
