by John Piper

Prayer is intentionally conveying a message to God. John Piper shows this includes asking for things (Matthew 7:7), praising him (Psalm 145:2), thanking him for his gifts, confessing your sins (Psalm 32:5), and even complaining to him with your troubles (Psalm 142:1) while guarding against a grumbling heart (Philippians 2:14).
You are called to pray privately in your inner room (Matthew 6:6), with your family as fellow heirs of grace (1 Peter 3:7), with two or three gathered believers, in corporate worship services, and everywhere by leaving the line open to God all day like never hanging up the phone.
We pray because Scripture commands it many times (1 Thessalonians 5:17, Luke 18:1), because asking in Jesus' name fills our joy (John 16:24), because it is a staggering privilege that causes events to happen which would not occur otherwise (James 4:2), and because it glorifies the Father and the Son (John 14:13).
All your praying finds unity and depth when it centers on the first request of the Lord's Prayer. John Piper explains that asking God to hallow his name means pleading for his name to be treasured above all else in every heart and situation.
This is the main text that corrects hypocritical prayer and sets the priority on praying for God's name to be hallowed.
The Spirit helps us when we do not know how to pray as we ought, showing that prayer can include wordless groanings with meaning.
Jesus commands private prayer in your room away from others so your Father who sees in secret will reward you.
Husbands and wives are to live together as fellow heirs so their prayers will not be hindered, making family prayer a barometer of relational health.
Asking in Jesus' name fills our joy, showing prayer as the path to greater happiness in God.
Whatever you ask in Jesus' name, he will do it so the Father may be glorified in the Son, revealing prayer's chief purpose.
Calling on God in trouble leads to deliverance so that he is glorified, summing up why we pray.
This week begin every prayer, every car ride, and every new task by asking God to hallow his name in your heart and in the lives of the people you love, then watch how that focus shapes the rest of what you say to him.
