(Psa 119:89 KJV) For ever, O LORD, thy word is settled in heaven.
God’s word is reliable; God’s truth doesn’t change. God’s wisdom and truth do not become dated. God’s truth is complete, His wisdom is perfect. He knows everything there is to know; He knows the past, the present, the future. Therefore, God’s truth doesn’t change. We can rely on God’s Word to be true. Trust His word; obey His commandments and rely on His promises.
