The Son of God incarnated Himself and died on the cross to redeem people.
Because of this sacrifice, Christians don't need to work to go to Heavens.
However, what if a Christian truly believes in Jesus and gives Him his life, but later commits a big sin? Like adultery, grand theft, murder, or rape...
Is that Christian immediately forgiven without doing anything? Without repenting? If that Christian does not need to work, then why being good? Is morality pointless? Does God send sinful people to Heavens because He died for them and so forgave them anyway? So Christians murderers will go to Heavens?
Or does that Christian need to work to repent? Do penance? Be purified? Go through Purgatory?
Some people say that actually this Christian was never really saved. They say true faith leads to good works.
However, that Christian actually had true faith, yet he still commits a big sin. How do you explain that some Christians really have faith in Jesus-Christ, but they still commit big sins?
King David was an adulterer and a murderer. And while the bible does not say as much, its a very real possibility that his initial interactions with Bathsheba were not consensual. And yet, God declared him a man after His own heart.
1 Samuel 13
"But now thy kingdom shall not continue: the LORD hath sought him a man after his own heart, and the LORD hath commanded him to be captain over his people, because thou hast not kept that -- which the LORD commanded thee."
God chooses David
1 Samuel 16
"..for the LORD seeth not as man seeth; for man looketh on the outward appearance, but the LORD looketh on the heart."
God declares that His Spirit would not depart from him
1 Samuel 16
"Then Samuel took -- the horn of oil, and anointed -- him in the midst of his brethren: and the Spirit of the LORD came upon David from that day forward."
David sins grievously, but remains a man after Gods own heart
1 Kings 15
"Nevertheless for David's sake did the LORD his God give him a lamp in Jerusalem, to set up his son after him, and to establish Jerusalem: Because David did
that which was right in the eyes of the LORD, and turned not aside from any
thing that he commanded him all the days of his life, save only in the matter of Uriah the Hittite."
David eventually repented of his sin against God.
And he paid dearly for his transgression.
2 Samuel 12
"Now therefore, the sword shall never depart from your house, because you have despised Me, and have taken the wife of Uriah the Hittite to be your wife.’ Thus says the Lord: ‘Behold, I will raise up adversity against you from your own house; and I will take your wives before your eyes and give
them to your neighbor, and he shall lie with your wives in the sight of this sun. For you did
it secretly, but I will do this thing before all Israel, before the sun.’ ”
So David said to Nathan, “I have sinned against the Lord.”
But God never departed from David, or repented of the promises that He made to Him.
2 Samuel 7
"When your days are fulfilled and you rest with your fathers, I will set up your seed after you, who will come from your body, and I will establish his kingdom. He shall build a house for My name, and I will establish the throne of his kingdom forever. I will be his Father, and he shall be My son. If he commits iniquity, I will chasten him with the rod of men and with the blows of the sons of men. But My mercy shall not depart from him, as I took
it from Saul, whom I removed from before you. And your house and your kingdom shall be established forever before you. Your throne shall be established forever."
Can we establish any doctrine upon these verses? Perhaps, maybe someone already has, I wouldn't know, I'm no theologian.
Can we argue endlessly over such doctrines, established or not?
Oh yes we can, and do.
I see several things in these passages that in my simple mind, and with my simple faith, cannot be argued.
God chooses whom He will.
God gives His Spirit unto whom He chooses without repentance.
Whom God chooses, God will correct and lead to repentance.
God sees the heart.
God reveals His heart to men.
And Gods heart, is that of a Father to His children
