This is a habit that has to be formed

Devote yourselves to prayer with an alert mind and a thankful heart. (Colossians 4:2 NLT)

 We are called to be in continual relationship with God, in a sense having an ongoing dialogue with Him, talking to Him, asking His guidance, praising Him, listening to Him throughout our day.
 We think thousands of thoughts every day, and these can be turned into prayers. This is a habit that has to be formed, but it’s wonderfully effective in teaching you to truly “pray without ceasing.” You don’t have to think up things to pray for all day long; you just turn your thoughts into a prayer to the Lord.
 For example, if you wake up in the morning and think, “I’m so tired, I don’t know how I can get out of this bed,” you can change that into a prayer: “Lord, You know how tired I am and how I need Your strength for this day.” Or when you think, “I wonder how my kids are doing,” you can pray, “Lord, do bless and keep the children, whatever they’re doing right now. Protect them and give them lots of love and kindness and wisdom.”
 Even with your positive thoughts, like, “Oh, what a gorgeous day,” you can turn it into praise to the Lord. “Thank You, Jesus, for giving us such a beautiful day.” —Maria Fontaine [1]

 Prayer is not monologue, but dialogue. God’s voice in response to mine is its most essential part. —Andrew Murray
