Plenty of people started out good but went bad like King Saul, Elisha's servant, Ananias and Sapphira. Paul says it's impossible to renew unto repentance any saints that fall away. Peter says something similar. The Unmerciful Servant was forgiven and debt free, but had his original punishment and debt reinstated because he told his master this far and no further...he wouldn't allow the grace shown him to expel the greed in his heart. We can jump outta God's hand anytime we want, and like the dogs and pigs, plenty return to the filth of this world.
" Started out good " ...Were not dealing with Santa here . let's look again at this verse . SEALED.....UNTO ...THE ........DAY OF REDEMPTION!!! .
AND AGAIN .
Eph 1
5Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will,
A believer is Guaranteed to be adopted which happens ...Rom 8.23 .
AGAIN .
Eph 1 .
13¶In 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 ( GURANTEE ) of our inheritance until the redemption of the purchased possession, unto the praise of his glory.
AGAIN
Rom 8 .
38For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come,
39Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.
AGAIN .
Eph 2
5Even when we were dead in sins, hath quickened us together with Christ, (by grace ye ARE saved
6And hath raised
us up together, and made
us sit together in heavenly
places in Christ Jesus:
SEATED IN HEAVENLY PLACES IN CHRIST JESUS . A believer is already spiritually resurrected.
We never earned our salvation by our efforts/ good deeds . We did nothing to earn it . We can't do anything to maintain or keep it . Thats not how salvation works .
