Because of the love of Christ Jesus and the church He built through His disciples we are taught how to live Godly lives, (2 Peter 3:10-11) remind Peter’s readers of The Day of the LORD and the coming judgement. Thanks to the letters we can learn what Godly living is.
Jude 24 “Now to Him who is able to protect you from stumbling and to make you stand in the presence of His glory, without blemish and with great joy, 25 to the only God our Savior, through Jesus Christ our LORD, be glory, majesty, power, and authority before all time, now and forever. Amen”
