One of the simplest prayer formats of prayer I have tried over the years is ACTS - an acronym for Adoration, Confession, Thanksgiving, and Supplication. I normally spend about 10 minutes on each of these four parts, allowing for 30-40 beautiful minutes of undistracted prayer in my day.
Here's what I do at each segment:
"Bless and affectionately praise the Lord, O my soul,
And all that is [deep] within me, bless His holy name.
Bless and affectionately praise the Lord, O my soul,
And do not forget any of His benefits."
I tell God how much He means to me. I spend time praising God for all the His Son, Jesus, is to me. I normally loosely follow a "litany of praise", which you can find here.
"God made him who had no sin to be sin for us, so that in him we might become the righteousness of God."
2 Corinthians 5:21
I tell God my sins and failures, not so I can be forgiven but because I know I am forgiven. But confession doesn't stop at telling God our sins, we must also tell our souls the forgiveness and righteousness that we have in the everlasting sacrifice of Jesus Christ. I normally do this latter part out loud, making sure that I am articulating loudly and clearly who I am in Christ.
"I will praise God's name in song and glorify him with thanksgiving."
I have discovered that gratitude is one my best weapons against the bitter, painful, and destructive circumstances that life throws at me. I have so much to be thankful for - not just for what God has done for me, but more importantly who He is to me. At this segment of my prayer time, I make sure I give God a "sacrifice of praise" because He is worthy, but also because it's healthy for my soul!
"Be anxious for nothing; but in everything with prayer and supplication, and thanksgiving, make your request be made known to God. And the peace of God which surpasses all understanding will guard your hearts and minds in Christ Jesus."
I go through this segment by creating a "prayer list". I pray for myself, my wife and kids, different needs in the church, and people that come to mind.
