Acts 1:15 And in those days Peter stood up in the midst of the disciples, and said, (the number of names together were about an hundred and twenty,) 1:16 Men and brethren, this scripture must needs have been fulfilled, which the Holy Ghost by the mouth of David spake before concerning Judas, which was guide to them that took Jesus. 1:17 For he was numbered with us, and had obtained part of this ministry. 1:18 Now this man purchased a field with the reward of iniquity; and falling headlong, he burst asunder in the midst, and all his bowels gushed out. 1:19 And it was known unto all the dwellers at Jerusalem; insomuch as that field is called in their proper tongue, Aceldama, that is to say, The field of blood. 1:20 For it is written in the book of Psalms, Let his habitation be desolate, and let no man dwell therein: and his bishoprick let another take. 1:21 Wherefore of these men which have companied with us all the time that the Lord Jesus went in and out among us, 1:22 Beginning 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. 1:23 And they appointed two, Joseph called Barsabas, who was surnamed Justus, and Matthias. 1:24 And they prayed, and said, Thou, Lord, which knowest the hearts of all men, shew whether of these two thou hast chosen, 1:25 That he may take part of this ministry and apostleship, from which Judas by transgression fell, that he might go to his own place. 1:26 And they gave forth their lots; and the lot fell upon Matthias; and he was numbered with the eleven apostles.

Or as the writer of Hebrews had been inspired to write to such as your kind; where the things of the Lord and HIS Book are concerned...
Hebrews 5:11 Of whom we have many things to say, and hard to be uttered, seeing ye are dull of hearing. 5:12 For when for the time ye ought to be teachers, ye have need that one teach you again which be the first principles of the oracles of God; and are become such as have need of milk, and not of strong meat. 5:13 For every one that useth milk is unskilful in the word of righteousness: for he is a babe. 5:14 But strong meat belongeth to them that are of full age, even those who by reason of use have their senses exercised to discern both good and evil.
