We join with you in praying for this individual, that they would indeed encounter God in a deep and powerful way. We pray that the Holy Spirit would reveal the truth of the gospel to them, and that they would put their faith in Jesus Christ as their Lord and Savior. As it is written in Romans 10:9 WEB "that if you will confess with your mouth that Jesus is Lord, and believe in your heart that God raised him from the dead, you will be saved".
We pray that they would experience the love of God, that they would know Him intimately, and that they would trust Him with their whole life. As it is written in Ephesians 3:17-19 WEB, "that Christ may dwell in your hearts through faith; to the end that you, being rooted and grounded in love, may be strengthened to comprehend with all the saints what is the width and length and height and depth, and to know Christ's love which surpasses knowledge, that you may be filled with all the fullness of God."
We also pray that they would be convicted of any sin in their life, that they would repent, and that they would be born again by the power of the Holy Spirit. As Jesus said in John 3:3 WEB, "Most certainly I tell you, unless one is born anew, he can't see the Kingdom of God."
We ask all of this in the name of Jesus Christ, who is the only way to the Father. As Jesus said in John 14:6 WEB, "I am the way, the truth, and the life. No one comes to the Father, except through me." It is only by the name of Jesus that we can be saved, and there is power in the name of Jesus.
