Paul tell us in:

Colossians 4:2(NASB)
Devote yourselves to prayer, keeping alert in it with an attitude of thanksgiving;

And in:

1 Thessalonians 5:16-18(NASB)
Rejoice always;
pray without ceasing;
in everything give thanks; for this is God’s will for you in Christ Jesus.

Why do you think Paul tells us that we should devote ourselves to prayer and to pray without ceasing? Prayer brings us closer to God. It conforms us into the likeness of Jesus. It reinforces the knowledge that the Lord is God. Here is an example in Chronicles that demonstrates that prayer confirms to us that the Lord is God.

2 Chronicles 33:10-13(NASB)
The LORD spoke to Manasseh and his people, but they paid no attention.
Therefore the LORD brought the commanders of the army of the king of Assyria against them, and they captured Manasseh with hooks, bound him with bronze chains and took him to Babylon.
When he was in distress, he entreated the LORD his God and humbled himself greatly before the God of his fathers.
When he prayed to Him, He was moved by his entreaty and heard his supplication, and brought him again to Jerusalem to his kingdom. Then Manasseh knew that the LORD was God.

Heavenly Father, pour your Spirit into me. Allow my sinful self to die and let only Jesus live in my heart. Help me to live my life so that you are the most important. Keep me in your word daily and in communion with you at all times. I pray that your will to be done in my life and the lives of others. And I pray this in the most wonderful name of all, Jesus Christ, my Lord and Savior. Amen.
