Someone I know has 3 friends who are severely depressed, they have all either considered suicide or are considering suicide.
"Making a million friends is not a miracle, the miracle is making one friend who will stand by your side when millions are against you."
This person wants to be that kind of friend so his/her friends don't make a huge mistake. Pray for this person's strength and guidance to do so. Allow them to create a better environment built on trust and love for these people who are depressed.
I will not only pray that they the strength to deal with this situation, but alao that they will have the words to turn these 3 people towards Christ.
