You should worry about yourself. Either she is or isn’t. Your preaching on a deathbed is unseemly.
I'm with Bellflower, and I've seen persons actually committing themselves to Jesus Christ in their final moments.
It's one with opinions like you have given here that ought to be not only worrying, but under conviction for such a misplaced "compassion."
My first time was when my friend asked me to come to the hospital to talk to a man who was dying about The LORD. He had earnestly shared Jesus with the dying man to no avail. He thought that maybe I could reach him and asked me to come and visit with him. I did and my friend was right, he heartfully accepted The LORD as I prayed with him. That night he died. I will see him in heaven.
Since then it has been my great blessing to lead others dying and lost to a saving knowledge of Jesus Christ.
As long as someone has breath there is hope for them. God is faithful to answer our prayers. There is nothing more loving you can do for a person dying without Jesus than to pray for their salvation, and if you can share our LORD’s love and desire for them that they be saved. There is nothing worse than spending eternity separated from God. Not only should we pray for them, but we should pray earnestly for them.
