Paul writes Timothy in 2 Tim 2:22,
Flee the evil desires of youth and pursue righteousness, faith, love and peace, along with those who call on the Lord out of a pure heart. (NIV)
But keep away from youthful passions, and pursue righteousness, faithfulness, love, and peace, in company with others who call on the Lord from a pure heart. (NET)
Ray Van Neste observes in the ESV Study Bible,
The pursuit of right is not to be done alone but along with other believers. Connection with the community of faith is essential for both progress in sanctification and perseverance in the faith.
Similarly, the NET Bible note observes,
In company with others who call on the Lord from a pure heart alludes to the value of the community of believers for the development of Christian virtues.
