He who overcomes shall possess these things, and I will be his GOD, and he shall be my son. But as for the cowardly and unbelieving, and abominable and murderers , and fornicators and sorcerers, and idolaters and all liars , their portion shall be in the pool that burns with fire and brimstone, which is the second death. Yes, but not as some non-Catholics believe that it is a one sided process completed by Jesus Christ alone. He did His part, now it is up to each one of us to do our part by our co-operation with His unlimited sacrifice on the cross. Nevertheless, Catholics realize that even the fulfilling of Our Lord's requirements for salvation is impossible without the free gift of His grace.
Salvation is an ongoing process throughout our lives.
It is a life long struggle. But that servant who knew his masters will, and did not make ready for him and did not act according to his will, will be beaten with many stripes . Now the works of the flesh are manifest, which are immorality, uncleanness, licentiousness, idolatry, witchcrafts, enmities, contentions, jealousies, anger, quarrels, factions, parties, envies, murders, drunkenness, carousings, and suchlike. Therefore, brethren, strive even more by good works to make your calling and election sure. For if you do this, you will not fall into sin at any time.
