Philippians 1:20
20 According to my earnest expectation and my hope, that in nothing I shall be ashamed, but that with all boldness, as always, so now also Christ shall be magnified in my body, whether it be by life, or by death.
With every word and action a Christian does in life should magnify Christ. When they pass on it should be known that even until the end that they walked the walk and talked the talk as a Christian. It should not just be said that they went to this church on Sunday or that they believed in God. People should be speaking of how they could see and feel Christ in you. Christians should have a boldness that people know that we stand in our faith. I am not saying that people should praise you. It is okay if someone never even knows your name, because if Christ is magnified through your actions you have done what a Christian is supposed to do. Our job is to magnify Jesus Christ and his teachings through our day to day lives. Then when we pass on and people are sharing memories about us, it leads back to Christ.
