Jude 1:3

3 Beloved, while eagerly preparing to write to you about the salvation we share, I find it necessary to write and appeal to you to contend for the faith that was once for all entrusted to the saints.

Jude 1:3 In-Context

1 Jude, a servant of Jesus Christ and brother of James, To those who are called, who are beloved in God the Father and kept safe for Jesus Christ:
2 May mercy, peace, and love be yours in abundance.
3 Beloved, while eagerly preparing to write to you about the salvation we share, I find it necessary to write and appeal to you to contend for the faith that was once for all entrusted to the saints.
4 For certain intruders have stolen in among you, people who long ago were designated for this condemnation as ungodly, who pervert the grace of our God into licentiousness and deny our only Master and Lord, Jesus Christ.
5 Now I desire to remind you, though you are fully informed, that the Lord, who once for all saved a people out of the land of Egypt, afterward destroyed those who did not believe.
