Lord Jesus Christ, Son of God, have mercy on me a sinner
A practice I started recently was after I get in bed at night is to pray the Jesus prayer about 20-25 times (I am not legalistic on how many times). I pray for and meditate on Christ mercy and forgiveness of my sins. I rest in the fact he will forgive my sins (1 John 1:9) and deliver me from evil thoughts and temptations (Matthew 6:13)
I find it.
1. Reminds me that Jesus is with me while I sleep.
2. Cleanses my mind of evil thoughts to focusing on Jesus.
3. Helps me to relax.
Try praying "Lord Jesus Christ, Son of God, have mercy on me a sinner" as you prepare for sleep tonight.
Psalm 63:6-7 ... I remember thee upon my bed, and meditate on thee in the night watches Because thou hast been my help, therefore in the shadow of thy wings will I rejoice.
