1 Corinthians 16:13-16

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. [Ps 31:24] Let everything you do be done in love [motivated and inspired by God’s love for us]. Brothers and sisters, you know that those of the household of Stephanas were the first converts in Achaia, and that they have devoted themselves for ministry to God’s people—now I urge you to be subject to such leaders [treating them with courtesy and respect], and to everyone who helps in the work and labors [for the benefit of yourselves and the church].
