Christianity isn't a boxed-in, boring life of can or can't do's. It's a life filled with blessing when you realize who you become in Christ.
Whenever we don't have the words to pray, or possibly don't feel like it, we can lean on Jesus' words to "pray in this way." The Lord's prayer addresses everything we need for today, starting with knowing who God is.
And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus. Phil 4:7
For everything that was written in the past was written to teach us, so that through the endurance taught in the Scriptures and the encouragement they provide we might have hope. Romans 15:4
