I think it’s important to always keep people in your prayers. Especially those who reject the gospel or start ignoring you because all you want to talk about is God etc.
I think we should always encourage people to the gospel and Gods word and when they reject it pray without ceasing for them. Lovingly send some encouragement their way, invite them to church, church functions, bible study etc do these things while praying for them daily.
