1 Corinthians 15.58 Therefore, my beloved brothers, be steadfast, unmovable, always abounding in the work of the Lord, knowing that your labor is not in vain in the Lord.

(see also Revelation 3.11 Behold, I come quickly: hold that fast which you have, that no man take your crown, & 1 Corinthians 16.13 Watch, stand fast in the faith, show yourselves to be men, be strong, & Ephesians 4.27 Neither give place to the devil, & 1 Peter 5.8-9 Be sober, be vigilant; because your adversary the devil, as a roaring lion, walks about, seeking whom he may devour: Whom resist steadfast in the faith).
