The demands of Jesus are difficult just because they require us to do something extraordinary - Albert Schweitzer
Someone once remarked that if our Faith journey was too easy, then perhaps we had settled into a comfort zone. Christianity is tough. It has been difficult for people to truly follow Jesus in the midst of a world that ignores His voice. If you are experiencing a tough time in your faith, don't be surprised by it - "the demands of Jesus are difficult!"
But also remember that God has not left you during this time. He is nearer than we think.
