You have posted a satanic lie. To be in Heaven, where the trying of the life works since being born from above takes place, ONLY those already saved are in the family of God's life. God does the purifying WHEN you believe Jesus is The One Whom God has sent for salvation of the individual descendants from ADAM. You arrive IN HEAVEN for the Bema Seat of Christ THEN the Glory of The Lord tries the works, whether they are wood, hay, and stubble, or gold, silver, and precious stones. And if you read The Revelation carefully, you will see those ‘precious stones’ in the edifice called the New Jerusalem, coming down OUT OF HEAVEN for the Millennial Reign of Christ.
There is a huge reason why Paul wrote to Timothy to study 'to show himself approved'. Paul didn't say absorb the dictates of the magicsteeringthem to show you know the dogmas of catholiciism, he told Timothy to study, the scriptures and the writings available from the Apostles at that time.
