When I became a Christian I was in a similar position, in that none of my family were Christians. So I did all the things you’ve suggested – I prayed, I talked at every opportunity, I left tracts around the house and so on. And nothing happened.
So I start giving God grief, “Heh! I love my family. I’m praying, witnessing, doing all I can. Why haven’t You saved them.” Those weren’t the exact words, but that was certainly the gist of it: “God, I’m doing my bit, You don’t seem to be doing Yours.”
The Lord stopped me with a simple sentence. It was a sentence that gave me both peace and reassurance. And, as so often in the ministry of Jesus, the sentence was a question. He said, “Who loves them more?” Well that certainly stopped me in my tracks and put it into perspective. Yes, I love my family; but God sent Jesus to die for my family. Who loves them more? He does.
So I carried on with the praying and the witnessing, but without the pressure that, “I’ve got to get them converted or they’ll go to hell.” Which is very common – and understandable – amongst new Christians. One by one, over many years, my immediate family came to Christ.
My suggestion is to do whatever seems right to you, but without any pressure on you or them, without any sense of panic about them dying before they convert and so on; and always remembering, especially in the face of little apparent progress, “Who loves them more?”
God bless you
