Galatians 3:3: Are you so foolish? Having started with the Spirit, are you now ending with the flesh?
Jesus did not say we would have a nice easy ride after we become Christians. No, he warned us we would have all manner of people fighting against us, blaming us and doing things against us because we chose to listen to him!
It is, therefore, a much easier task to give in to the worldly pleasures and ways instead of following that narrow, hard. winding path we should be leading!
God wants to give us the strength and wisdom to walk that narrow path - as long as we are willing to listen to him and let him lead us!
