Then Jesus told his disciples, "If any man would come after me, let him deny himself and take up his cross and follow me. For whoever would save his life will lose it, and whoever loses his life for my sake will find it. 

Matthew 16:24-25

“Never forget that the way which leads to heaven is narrow; that the gate leading to life is narrow and low; that there are but few who find it and enter by it; and if there be some who go in and tread the narrow path for some time, there are but very few who persevere therein.”
