“To the praise of the glory of his grace, wherein he hath made us accepted in the beloved.”  
Ephesians 1:6

He made us accepted in the beloved, our eternal location has been revealed to us by God, we are not found ‘in sin’, ‘in guilt’, ‘in disobedience’, ‘in rejection’ or ‘in shame’, we are found, fully accepted ‘in the beloved!’ That’s our location now, as far as God is concerned.
This emphasizes the fact that nothing is too good for us:
“The Lord takes care of me as his sheep; I will not be without any good thing.”  Psalms 23:1, BBE

‘to the praise of the glory of his grace’, this means his grace will be so lavished on us in astounding glory that people would praise him and his grace at work in our lives.
It means we would so walk in ease where others might seem stuck that people will just have to wonder at the grace of God on our lives.
This is one of the blessings and realities of our being born again children of God. Contemplate on this reality!
