I am not ready to go to Heaven

I will not be ready until I know that all of my loved ones are also saved! Like my youngest son...It's like familliarity breeds contempt! All of the miracles! I once prayed that he have supernatural strength to turn on the tap outside, and he came inside and said he had supernatural strength just like I prayed for him, he told his sister about it but soon disreguarded it. Stories about people at the hospitals being healed, means nothing to him, he seems to think that Christianity is superstition to get people to be good. I've tried telling him about God's grace He made Him He who knew no sin became sin for us so that we might have the righteousness of God, That God's grace is a free gift! Not earned by works! And that there are videos of trumpet sounds around the world, like that in the book of Revelation! He has every reason to believe but he thinks he's too smart to rely on the bible. I'm so so sad for my kids. If anyone should believe it should be them!!! Knowing that their mom hears Angels singing!!!! Like who's other parent's have that??? I did hear my daughter tell her best friend and cousin that she wanted to go to Heaven some day, her cousin then said that there is no Heaven or Hell! I told my daughter that if there is a seed of faith that the devil will come up and snatch it if he could using any means he could even using her cousin....My daughter disregarded me. Sigh! I love my children I strongly desire to go to Heaven with them too, but I don't want to push them over the edge, where there is no return and harden their hearts. Please God, Jesus save my family! Only then will I be happy to go to Heaven in the end. I don't want to go alone!
