Put it into practice!
"Finally, brothers, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable — if anything is excellent or praiseworthy — think about such things. Whatever you have learned or received or heard from me, or seen in me — put it into practice!" Philippians 4:8-9
You see the perfection of the Apostle's method. In verse 8 he has dealt with the realm of thought. Ah, but the Apostle knows the subtle danger that is always confronting us . . .
the danger of being content with theoretical knowledge,
the danger of being satisfied with doctrine only,
the danger of failing to put into practice, that which we know.
You can be a great student even of the Bible — and live a life that is utterly contrary to it!
It is the masterpiece of Satan to make us put theory and practice into separate watertight compartments — to make men so interested in the Book, that they forget to apply its teaching. "Whatever you have learned or received or heard from me, or seen in me," says Paul, "put it into practice!"

"It is not the knowing, nor the talking, nor the reading man, but the doing man — who at last will be found the happiest man!" Thomas Watson
