19 Behold, at that time I will deal with all who afflict you; I will save the lame, And gather those who were driven out; I will appoint them for praise and fame In every land where they were put to shame. 20 At that time I will bring you back, Even at the time I gather you; For I will give you fame and praise Among all the peoples of the earth, When I return your captives before your eyes,” Says the LORD. Zephaniah 3:19-20
God making you famous is actually a redemptive blessing in the Scriptures, though obviously it isn't for the faint of heart. It's a part of the Abrahamic blessing that is ours in Christ that's mentioned in Galatians 3. Genesis 12:2 says He'll make your name great. Isaiah 61:9 says Christ's spiritual descendants would be known among the nations and all who would see you would acknowledge that this is His blessing on your life.
It is a part of finishing one's course with joy and it is part of the calling to be conformed to the image of Christ, since He's famous. Zephaniah 3:19 says it's an appointment, so although it's unquestionably a part of one's ambassadorship in 2Corinthians 5, it's not something to be sought by fleshly carnal means, but is a part of His equiping the saints for His service.
The book of Zephaniah is about Him tearing down idolatry in the earth and the leaders in false paradigms. His wrath revealed in Zephaniah must be understood in that light, as well as His songs over the redeemed and giving them fame. It is intended to fill the gap He's created by tearing down false religions and institutions as He seeks to exalt His own wisdom and salvation in the earth.
Being full of His Word instead of flirting with all Scripture reveals He is tearing down is extremely important so that one's exaltation by the Hand of the Lord isn't going to end in shame and disgrace in one's own life. Zephaniah 3:19-20 says He will deal with those who have afflicted us and He will save the lame from their lameness. Therefore, His intent to exalt you in the eyes of all isn't meant to add to shame you've known, but is His vindication. Read Deuteronomy 8 very carefully on this.
