I've heard prayer described as one of those things more caught than taught. Our direct line of communication with God is a spiritual discipline that cannot be over looked. It is a weapon of spiritual warfare and needed on a daily. continuous basis.
“Rejoice always, pray without ceasing, give thanks in all circumstances; for this is the will of God in Christ Jesus for you” (1 Thessalonians 5:16-18)
Historically the first week of May is set aside as the National Week of Prayer, the first Thursday in May being the National Day of Prayer. Over the years I have had the privilege to attend a few special prayer breakfasts with special speakers and programs for this day. When God's people pray something amazing happens.
Prayer gives us access to the peace of God in all circumstances.
Don’t worry about anything, but in everything, through prayer and petition with thanksgiving, present your requests to God. 7 And the peace of God, which surpasses all understanding, will guard your hearts and minds in Christ Jesus. Philippians 4:6-7
It opens up our hearts with expectation to what God wants to do.
I pray that the eyes of your heart may be enlightened in order that you may know the hope to which he has called you, the riches of his glorious inheritance in his holy people, Ephesians 1:18
