How do I really know Jesus is Our Joyous Kinsman Redeemer? 

“Fear not, for you will not be put to shame; 

And do not feel humiliated, for you will not be disgraced; 

But you will forget the shame of your youth, 

And the reproach of your widowhood you will remember no more. 

5 “For your husband is your Maker, 

Whose name is the Lord of hosts; 

And your Redeemer is the Holy One of Israel, 

Who is called the God of all the earth. 

6 “For the Lord has called you, 

Like a wife forsaken and grieved in spirit, 

Isaiah 54 (NASB)
