Keep Alert by Joyce Meyer

Blessed (happy, fortunate, and to be envied) are those servants whom the master finds awake and alert and watching when he comes. Truly I say to you, he will gird himself and have them recline at table and will come and serve them!
- Luke 12:37

In Ephesians 6:10 God's word teaches, Be strong in the Lord [be empowered through your union with Him]; draw your strength from Him [that strength which His boundless might provides]. We are to put on God's armor so we won't be deceived by the devil. Verse 16 says, Lift up over all the [covering] shield of saving faith, upon which you can quench all the flaming missiles of the wicked [one].

In verse 18 we are also told to pray at all times (on every occasion, in every season) in the Spirit, with all [manner of] prayer and entreaty. To that end keep alert and watch with strong purpose and perseverance, interceding in behalf of all the saints (God's consecrated people) (emphasis mine).
