In our worldly perceptions of Jesus, we tend to embrace the kindness of his love ('be encouraged') but not the discipline of his love ('and sin no more'). But with the whole scope of his love, or maturity in Christ, we begin relying on him for guidance where we would prefer him to walk beside us rather than behind us.
As followers of Christ, we are to be careful not to remain victims of the many cultural presuppositions of who he is, and what he teaches, insofar as taking for granted our own caricatures of him. Let it boil in both mind and heart the question, 'If Jesus were to appear today, how many of us would actually recognize him and his teachings (or would it simply be a recount of his first visit)?
If Christ is God, He cannot sin, and if suffering was a sin in and by itself, He could not have suffered and died for us. However, since He took the most horrific death to redeem us, He showed us in fact that suffering and pain have great power.
When you suffer, you are being conformed to the image of Jesus. When you pray, you are being made holy in the image of Jesus. When you quietly serve a person in need, you are being shaped into the image of Jesus. When you generously give, your heart is being remade into the image of Jesus, our Lord and Savior.
