Father in Heaven,
I lift up ak and her friend to You. I pray that You will send the right people into his path to encourage him. I pray that You will bring him closer to You and away from these desires to commit suicide. I pray that You will show him a new perspective on life and give him a renewed vision.
in Jesus' Name, Amen.
ak, if you can't handle this, maybe you should seek help from someone in your church who is able to help you. Don't be stressed out. We have got to let God be God and not take all responsibility to ourselves. Pray for your friend and do practical things like spend time with him or encourage him in a hobby. Ask God for wisdom on practical ways to help him.
Find out what is the root of the problem if you can and take steps to help him. But again if this is too big of a task for you and since you are female and might have problems getting too close, maybe you can get help from a spiritual leader in your church.
