Wonderful book "Future Grace" by John Piper. I can not stop reading it. I recommend it. I do not know if it is available in Portuguese. To give you an idea take a look below and enjoy it.
Future Grace:
"Trust in the Lord with all thine heart;
and lean not unto thine own
understanding.
In all thy ways acknowledge him
and he shall direct thy paths."
Prov. 3:5,6
"Over the years, I have come to see that this passage is a call to live by faith in future grace. The call to live by faith is in the words, "Trust in the Lord with all thine heart." The reference to future grace is in the words, "He shall direct thy paths." Month after month, my mother counseled me to live by faith in future grace. She called me to trust the Lord, and showed me that the focus of my trust is what God promised to do for me in the future: "Son, the Lord will direct your paths; trust him, trust him."
"The ultimate purpose of this book is that God be prized above all things. I could also say that the ultimate purpose is the praise of the glory of God's grace. Is that prizing is the authenticating essence of praising. You can't praise what you don't prize. Or, to put in another way, God is most glorified in us when we are most satisfied in him."
