In different ways, we continuously prove that we fall short of the glory of God. This is revealed when we are challenged according to what we know and fail because within us is still the nature of evil, for example, imagine leaving your home in a cold day, you are on your way to work, you see a man in need of a jacket who is homeless, This man is cold and clearly shivering, by this time you've covered quite a distance plus you are wearing your favourite jacket. Would you give your very expensive, favourite jacket for this homeless man? Out of honesty, I really do not think so but maybe a few would, however, for the majority still unlikely. Such situations teach us about us, we still have it in us to be selfish, inconsiderate, greedy and other things given the right circumstances. We tend to put our needs first even when we have plenty at home ( given this scenario) and that is why Jesus said no one is good except God (Mark 10:18). Since we fall short of the glory of God we should count ourselves beyond blessed because of what Jesus did on the cross. We are saved through faith in Christ (Philippians 3:9). He is our righteous and even our good works cannot save us only by God's grace which is a gift (Ephesians 2: 8-9). This does not mean we shouldn't do good works, in fact, we should, it is a choice each day to imitate Christ and to die to oneself. To completely surrender and allow Him to live through you. Hopefully one day, years to come, we will look back and say we are better than we were before (speaking of being Christ-like) because at the end of the day we are working progress as the bible puts it, we are being moulded.
