I'll be praying for your grandfather. I'm guessing that he's pretty old now and he does not have as much time to live than most of us young people, so he needs to come to Jesus as soon as possible!
Hm. There is nothing wrong with not believing. Some people have reasons for not believing, and you cannot hate or judge them for that.
Even though I'm not Christian, I came here to learn.
Therefore, I'll pray. But, for this very reason:
That I hope your family will carry on living the good lives they have had.
We are happy that you have the desire to learn.
There is something wrong with not believing. There is a lot of things wrong with not believing in Christ. How can your sins be washed away without the blood of Jesus? Jesus was "the Lamb of God, who takes away the sin of the world." John 1:29
How can you come to God without Jesus? Jesus said, "No one can come unto the father except through me."
Jesus said, "The work of God is this: to believe in teh one he has sent."
God wants us to believe in Jesus so there is certainly something wrong with not believing. Hurting, you say that people have reasons for not believing and you cannot hate or judge them for that. Of course! As christians we are to love our enemies...we are not judging someone that does not believe in Christ...rather because we love them, we want them to come to Christ and believe in him.
