"For he who is least among you all--he is the greatest." (Luke 9:48)
The world rejects and hates Christianity because it teaches the truth. They know that Christians teach that we are all sinners. This sin results in death, because of this we need Jesus, the Son of God, who died and rose again to pay for our sins. They are not willing to accept that they are sinners, for they love their sinful life.
Many times people cannot except the fact that all the other nice people will not enter heaven. What if they never heard the gospel they say. All I can say to that is that God is a just God. Not only that but Jesus said those who knock the door will be opened to them, and those who seek will find. When Thomas asked Jesus how they will know the way, "Jesus answered, 'I am the way and the truth and the life. No one comes to the Father except through me.'" (John 14:6)
I will talk more on the questions sceptics of the faith have, but I will do so in the future posts. God bless.
