Thou wilt keep him in perfect peace, whose mind is stayed on Thee: because he trusteth in Thee. Trust ye in the LORD for ever: for in the LORD JEHOVAH is everlasting strength: For He bringeth down them that dwell on high; the lofty city, He layeth it low; He layeth it low, even to the ground; He bringeth it even to the dust. The foot shall tread it down, even the feet of the poor, and the steps of the needy. The way of the just is uprightness: Thou, most upright, dost weigh the path of the just. Yea, in the way of Thy judgments, O LORD, have we waited for Thee; the desire of our soul is to Thy Name, and to the remembrance of Thee. (Isaiah 26:3-8)
That doesn't mean we won't have trouble in this world, or that we won't experience sickness or disease, or that nothing will affect us as we sojourn here on this earth. It just means that with GOD we can go through anything He wills or allows us to experience, and He will be with us where ever He sends us. And one day, He will bring those of us who are truly His Home to be with Him.
Governments that forget GOD will be brought down. Religions that deny GOD or pervert His Word will be judged. Moral, social, and other systems that aren't based on GOD's Word will fail for they have no firm foundation. All that which is not firmly planted on the solid rock of Christ will, sooner of later, come crashing down; because the Truth will expose their falsehoods, because GOD is the Judge of all things, and because they have a shifting foundation.
Those that are in denial of their need of Jesus Christ, or have rejected Him as their Saviour and Lord are also weighed and judged. GOD has already condemned all who are not secure in Christ to His justice. But GOD, is not willing that any should perish, and calls everyone to repent, to surrender to Him on His terms. Jesus Christ offers you the free gift of salvation. Receive Him by faith today.
Trust Him, Believe His Word, and share the Hope of Jesus Christ with others you meet.
