One activity that will be seen when the gospels are examined is that Jesus spent much time alone in prayer seeking His Father. In Mark 1 it says He went out to pray a great while before day. In Luke 6:12 he spent an entire night in prayer before calling the specific twelve disciples as apostles. Occasionally what He prayed is written out, often very short prayers. Among them are at the tomb of Lazarus, during the entry to Jerusalem, prayer on the way to the garden of Gethsemane, and then very short, even single sentence prayers in the garden and on the cross. But the content of His daily prayers we don't know.
Throughout the Psalms there are many different Psalms that are the heart's cry of the psalmist that wrote them. Some like Psalm 22 are actually the content that Jesus quote from the cross and are typically called Messianic psalms. As Jesus did include the psalms when He told the men on the Emmaus road that they foretold of Him and quoted psalms as He taught. Now reading the Psalms yet again I wonder how many of theses psalms actually became the very words of His personal prayer life.
Hear my voice in the morning, O Lord: for in the morning will I direct me unto thee, and I will wait. For thou art not a God that loveth wickedness: neither shall evil dwell with thee. The foolish shall not stand in thy sight: for thou hatest all them that work iniquity. Thou shalt destroy them that speake lies: the Lord will abhor the bloody man and deceitful. But I will come into thine house in the multitude of thy mercy: and in thy fear will I worship toward thine holy Temple.
Psalms 5:3 - 7 GNV
Many times we use different Psalms as patterns for our own prayers. Would not the fully man Jesus Christ do the same?
