Lesson 2: Living Holy and Blameless in an Unholy Age

Key Scriptures:

• 2 Peter 3:10–14 – "But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up. Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness, Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat? Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness. Wherefore, beloved, seeing that ye look for such things, be diligent that ye may be found of him in peace, without spot, and blameless."

• 1 Thessalonians 5:23 – "And the very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ."

Exposition

1. The End-Time Context of Holiness

   • Peter ties holiness to the reality of the coming judgment (2 Peter 3:11).

   • In a time when moral decay is rampant, holiness becomes a prophetic sign of the Kingdom of God in us.

2. God’s Standard of Blamelessness

   • Holiness is not mere external morality—it is being set apart for God in heart, mind, and lifestyle.

   • 1 Thessalonians 5:23 shows the holistic nature of sanctification: spirit, soul, and body.

3. Practical Steps for End-Time Holiness

   • Guard your thought life (Philippians 4:8).

   • Avoid compromise with worldly values (Romans 12:2).

   • Maintain spiritual disciplines—prayer, Word study, fasting, fellowship.
