'Alert' in the Bible

“Be on guard and stay constantly alert [and pray]; for you do not know when the appointed time will come.

It is like a man away on a journey, who when he left home put his servants in charge, each with his particular task, and also ordered the doorkeeper to be continually alert.

Therefore, be continually on the alert—for you do not know when the master of the house is coming, whether in the evening, or at midnight, or when the rooster crows, or in the morning—

What I say to you I say to everyone, ‘Be on the alert [stay awake and be continually cautious]!’”

Blessed (happy, prosperous, to be admired) are those servants whom the master finds awake and watching when he arrives. I assure you and most solemnly say to you, he will prepare himself to serve, and will have them recline at the table, and will come and wait on them.

“But be sure of this, that if the head of the house had known at what time the thief was coming, he [would have been awake and alert, and] would not have allowed his house to be broken into.

Therefore be continually alert, remembering that for three years, night or day, I did not stop admonishing and advising each one [of you] with tears.

While they waited for the day to dawn, Paul encouraged them all [and told them] to have some food, saying, “This is the fourteenth day that you have been constantly on watch and going without food, having eaten nothing.

Be on guard; stand firm in your faith [in God, respecting His precepts and keeping your doctrine sound]. Act like [mature] men and be courageous; be strong.

With all prayer and petition pray [with specific requests] at all times [on every occasion and in every season] in the Spirit, and with this in view, stay alert with all perseverance and petition [interceding in prayer] for all God’s people.

Be persistent and devoted to prayer, being alert and focused in your prayer life with an attitude of thanksgiving.

So then let us not sleep [in spiritual indifference] as the rest [of the world does], but let us keep wide awake [alert and cautious] and let us be sober [self-controlled, calm, and wise].

So prepare your minds for action, be completely sober [in spirit—steadfast, self-disciplined, spiritually and morally alert], fix your hope completely on the grace [of God] that is coming to you when Jesus Christ is revealed.

The end and culmination of all things is near. Therefore, be sound-minded and self-controlled for the purpose of prayer [staying balanced and focused on the things of God so that your communication will be clear, reasonable, specific and pleasing to Him.]

(“Behold, I am coming like a thief. Blessed is he who stays awake and who keeps his clothes [that is, stays spiritually ready for the Lord’s return], so that he will not be naked—spiritually unprepared—and men will not see his shame.”)
