It doesn't take much to removed from this earth. Life is very fragile, so no one is safe and no one can plan a long life because it isn't certain. Since we have no control over what happens in future hours, we will waste no time discussing it. What we will talk about is getting ready to meet the moment when life ends and the Judgment begins.
Acts 16:30-34 30 He then brought them out and asked, "Sirs, what must I do to be saved?" 31 They replied, "Believe in the Lord Jesus, and you will be saved you and your household."32 Then they spoke the word of the Lord to him and to all the others in his house. 33 At that hour of the night the jailer took them and washed their wounds; then immediately he and all his household were baptized. 34 The jailer brought them into his house and set a meal before them; he was filled with joy because he had come to believe in God he and his whole household.
This is what everyone needs to do to get ready for the moment when eternality takes over. Today is the time, don't put it off any longer. Decide to give your life to Christ by doing what the jailer did. After his baptism, he was a happy man, because he knew he did what was needed in order to save his soul. If the soul is saved, the uncertainly of life, no longer matters.
