An admonition from the Bible and a good practice in life is to BE READY.
Mt 24:44; Luke 12:40 - Therefore you also be ready, for the Son of Man is coming at an hour you do not expect.
2 Timothy 4:2 - Preach the word! Be ready in season and out of season. Convince, rebuke, exhort, with all longsuffering and teaching.
1 Peter 3:15 - but sanctify Christ as Lord in your hearts, always being ready to make a defense to everyone who asks you to give an account for the hope that is in you, yet with gentleness and reverence
