In our modern days we think of "great preachers" of the past and of our day. Studying church history, a history of true believers certain names stand out bold for preaching, bold for translating, and so again, certain names are familiar to many. A biography of each and every one, were it even available, may surprisingly reveal that they weren't born that way. It may seem a bit facetious to make such a statement, "O, yes, everyone is born and grows up", but then it becomes important to actually take an account of their life before they became "famous". Even Paul when he was still mainly known as Saul really didn't become that well known until maybe fifteen years after his salvation when the Holy Spirit told the primarily Gentile church at Antioch of Syria to seperate Saul and Barnabas out to the work of the ministry. Even nearly eleven years before that moment the disciples in Jerusalem sent him home to Tarsus so that they could hopefully have peace in their own ministry.
Jesus had thirty years we largely know nothing about. But what we do know is that even at twelve His heart and mind were focused on His need to minister the Word. He was the Word then as much as He was when He began to minister. Those in the temple were already amazed at His knowledge, wisdom, and understanding as He asked and answered questions, and as we later read and learn:
Now when he was at Jerusalem at the Passover in the feast, many believed in his Name, when they saw his miracles which he did. But Jesus did not commit him self unto them, because he knew them all, And had no need that any should testify of man: for he knew what was in man.
John 2:23 - 25 GNV
So when considering that he did have a life growing up would not have Jesus reason prayed this psalm when He went off to talk with His Father? Having that question in mind before reading this psalm knowing that "He knew what was in man" it becomes disturbing to us at times because He still knows what is in us today. Preachers we know and have heard of in the past do not, but Jesus knows; so when we consider the possibility of Him praying:
Help Lord, for there is not a godly man left: for the faithful are failed from among the children of men. They speak deceitfully every one with his neighbour, flattering with their lips, and speak with a double heart.
Psalms 12:1 - 2 GNV
We might say, "If Jesus was honest with anyone..." (knowing full well He was honest with everyone) "...He was honest when He spoke with His Father." Praying this psalm would be no less honest. So often we read INTO the gospels that here was this always happy ever speaking to every man what they needed, but fail to recognize as a human the struggles were as real as ours today. It becomes very well possibly the only way He seemed positive and was able to stand against those that opposed Him and those who followed with Him was simply forcing Himself to make that time daily to spend with His Father, and in doing so present everything in this psalm to His Father about those around Him and even things that were challenges in His own heart dealing with such issues, a practice He may have engaged in from His youth.
