“Behold, I send My messenger, And he will prepare the way before Me. And the Lord, whom you seek, Will suddenly come to His temple, Even the Messenger of the covenant, In whom you delight. Behold, He is coming,” Says the Lord of hosts. “But who can endure the day of His coming? And who can stand when He appears? For He is like a refiner’s fire And like launderers’ soap. He will sit as a refiner and a purifier of silver; He will purify the sons of Levi, And purge them as gold and silver, That they may offer to the Lord An offering in righteousness.”‭‭Malachi‬ ‭3‬:‭1‬-‭3‬ ‭NKJV‬‬

Therefore let him who thinks he stands take heed lest he fall.‭‭I Corinthians‬ ‭10‬:‭12‬ ‭NKJV‬‬

What is your role in God’s will on earth? What are things we establish for His Kingdom come as His Children? This, then, is how you should pray: ‘Our Father in heaven, hallowed be your name, your kingdom come, your will be done, on earth as it is in heaven. Give us today our daily bread. And forgive us our debts, as we also have forgiven our debtors. And lead us not into temptation, but deliver us from the evil one.’‭‭Matthew‬ ‭6‬:‭9‬-‭13‬ ‭NIV‬‬

“I have been crucified with Christ and I no longer live, but Christ lives in me. The life I now live in the body, I live by faith in the Son of God, who loved me and gave himself for me. I do not set aside the grace of God, for if righteousness could be gained through the law, Christ died for nothing!””‭‭Galatians‬ ‭2‬:‭20‬-‭21‬ ‭NIV‬‬

that Christ may dwell in your hearts through faith; that you, being rooted and grounded in love, may be able to comprehend with all the saints what is the width and length and depth and height— to know the love of Christ which passes knowledge; that you may be filled with all the fullness of God.‭‭Ephesians‬ ‭3‬:‭17‬-‭19‬ ‭NKJV‬‬

“Therefore, brethren, be even more diligent to make your call and election sure, for if you do these things you will never stumble;”‭‭II Peter‬ ‭1‬:‭10‬ ‭NKJV‬‬
