some of them can be Christians some of them are not…
old friends…
#1-(if they don’t know )tell them you are a Christian
#2-take them with you to church
#3-tell them stories about Jesus
#4-pray a lot every night and day 24h
#5-ask them what do they think about Him
#6-tell them if they are really my friends they should change with you and live life right
#7-if non work you will have to move on and let God do the rest
I hope and Pray that you find the rights friends and see them all someday in heaven
God Bless
