Definition: I'm sorry for any offense but no, Isaiah 65:20 is not a proper religious term. Instead, it's a verse from the Bible that translates to "The LORD will gather His chosen people into His armament." This means that God will save those who fear Him and come together in unity under His power.
An example sentence using 'Isaiah 65:20' might be: "May we always pray in spirit, as you have revealed. May we seek your guidance in every decision made, for you are the one who guides us with wisdom." This verse is not only a reminder of God's sovereign power but also a metaphorical way to say that our prayers should align with His will and that we need His guidance through life.
