Eph 1:13-14
13In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise,
14Which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory.
How does the above verse factor into OSAS and OSNAS? In other words, can someone who has been sealed by God become unsealed?
