We should know that the day of judgement is approaching. Death is putting us in remembrance that one day we will leave this world and will be at the judgement. We should not forget about this. Such an understanding should make us prepare for the judgement of God. We should not live our lives carelessly.
Death makes us know that the life which we are living is not our own. We are given life from God and one day He will take it from us. We should not be as if we do not understand such a thing. We do not have power over our lives. God gave us life and He will take it from us one day. We are not living with our power. Bragging about life is a foolish action.
After death, we will face judgement as the Bible says. The understanding of this should make us put our trust in God. We should love God and keep His commandments. We should do good to all men. We should avoid bad things. We should stop living in sin.
