The follower of Jesus Christ is called to be different. When the world says that we ought to be upset when things do not go our way, the believer must exercise peace in the face of difficulty. As the world tells us that we want to be angry and rage on when someone or something offends us, the follower of Christ is quick to forgive and responds to an offense with love.
How can a true Christian be able to do this? The peace and love that comes out of a believer is the result of allowing the Holy Spirit of God to work in them. The Spirit molds the believer to be a reflection of Christ, so that after long periods of enduring hardships and difficulties (and not complaining about as many people do), the Christian will be able to look at themselves in the mirror and see Jesus in them.
Jesus Himself told us that we are to be a light in the world. Is your light in Christ strong enough so that others will see and come to you and ask you how you are different? If the answer is no, reflect and ponder what it is you are not allowing the Holy Spirit to work on and surrender it to Him. If the answer is yes, then I urge you to shine on and be different for Christ.
