How can we know The Way

In John 14:5, Thomas asked a great question by saying ‘if we don't know where you are going, how we can know the way?’ Normally if you don't know a place it's hard to find your way there. But Jesus responds ‘I am the way.’ We know it's not an easy road because even Jesus went through trials, humiliation, betrayal, and hate. However, still He shows love and mercy at all time.
