Jesus, the Son of God and Lord of all things, spent whole nights in prayer while He lived on earth. In those night-long encounters, Jesus communed with His Father. His prayers were not just petitions to get something.

Prayer does involve petition and intercession, but it also includes communion.
Communion is the line that connects our soul with the battery of God's power. When this line is down, our petitions are but idle chatter. God's power must flow into our lives as we bow before Him and recognize Him as Lord of all. Communion with God is a great privilege and the most important element of prayer.
