Philippians 2:12-29. The Apostle Paul urged the believers to work out their salvation with fear and trembling. Yes, salvation is past tense (for by grace have you been saved), present tense (work out your own salvation) and future tense (you will be saved). God is independent of time (He existed before time and space. Time and.. space only has meaning after creation of matter). Paul ended the chapter talking about Timothy and Epaphroditus.
Isaiah 63. The day of the Lord’s vengeance is coming where “the grapes of wrath are trod” and there was no one to help. Then God will show His mercy and provide salvation, but will people listen?
Isaiah 64. A prayer of petition and penance: “All our righteousness are as filthy rags”
Psalm 81, of Asaph. A Psalm for the Feast of Tabernacles.
