Many Christian's believe that once we are saved then we can't move away from God's salvation. There are many threads written about this. But it is some of these passages that cause to me think otherwise.
The Vine and the Branches
15 “I am the true vine, and my Father is the gardener. 2 He cuts off every branch in me that bears no fruit, while every branch that does bear fruit he prunes[a] so that it will be even more fruitful. 3 You are already clean because of the word I have spoken to you. 4 Remain in me, as I also remain in you. No branch can bear fruit by itself; it must remain in the vine. Neither can you bear fruit unless you remain in me. 5 “I am the vine; you are the branches. If you remain in me and I in you, you will bear much fruit; apart from me you can do nothing. 6 If you do not remain in me, you are like a branch that is thrown away and withers; such branches are picked up, thrown into the fire and burned. 7 If you remain in me and my words remain in you, ask whatever you wish, and it will be done for you. 8 This is to my Father’s glory, that you bear much fruit, showing yourselves to be my disciples.
The Parable of the Bags of Gold
14 “Again, it will be like a man going on a journey, who called his servants and entrusted his wealth to them. 15 To one he gave five bags of gold, to another two bags, and to another one bag,[a] each according to his ability. Then he went on his journey. 16 The man who had received five bags of gold went at once and put his money to work and gained five bags more. 17 So also, the one with two bags of gold gained two more. 18 But the man who had received one bag went off, dug a hole in the ground and hid his master’s money.
19 “After a long time the master of those servants returned and settled accounts with them. 20 The man who had received five bags of gold brought the other five. ‘Master,’ he said, ‘you entrusted me with five bags of gold. See, I have gained five more.’
21 “His master replied, ‘Well done, good and faithful servant! You have been faithful with a few things; I will put you in charge of many things. Come and share your master’s happiness!’
22 “The man with two bags of gold also came. ‘Master,’ he said, ‘you entrusted me with two bags of gold; see, I have gained two more.’
23 “His master replied, ‘Well done, good and faithful servant! You have been faithful with a few things; I will put you in charge of many things. Come and share your master’s happiness!’
24 “Then the man who had received one bag of gold came. ‘Master,’ he said, ‘I knew that you are a hard man, harvesting where you have not sown and gathering where you have not scattered seed. 25 So I was afraid and went out and hid your gold in the ground. See, here is what belongs to you.’
26 “His master replied, ‘You wicked, lazy servant! So you knew that I harvest where I have not sown and gather where I have not scattered seed? 27 Well then, you should have put my money on deposit with the bankers, so that when I returned I would have received it back with interest.
28 “‘So take the bag of gold from him and give it to the one who has ten bags. 29 For whoever has will be given more, and they will have an abundance. Whoever does not have, even what they have will be taken from them. 30 And throw that worthless servant outside, into the darkness, where there will be weeping and gnashing of teeth.’
The Parable of the Sower
13 That same day Jesus went out of the house and sat by the lake. 2 Such large crowds gathered around him that he got into a boat and sat in it, while all the people stood on the shore. 3 Then he told them many things in parables, saying: “A farmer went out to sow his seed. 4 As he was scattering the seed, some fell along the path, and the birds came and ate it up. 5 Some fell on rocky places, where it did not have much soil. It sprang up quickly, because the soil was shallow. 6 But when the sun came up, the plants were scorched, and they withered because they had no root. 7 Other seed fell among thorns, which grew up and choked the plants. 8 Still other seed fell on good soil, where it produced a crop—a hundred, sixty or thirty times what was sown. 9 Whoever has ears, let them hear.”
18 “Listen then to what the parable of the sower means: 19 When anyone hears the message about the kingdom and does not understand it, the evil one comes and snatches away what was sown in their heart. This is the seed sown along the path. 20 The seed falling on rocky ground refers to someone who hears the word and at once receives it with joy. 21 But since they have no root, they last only a short time. When trouble or persecution comes because of the word, they quickly fall away. 22 The seed falling among the thorns refers to someone who hears the word, but the worries of this life and the deceitfulness of wealth choke the word, making it unfruitful. 23 But the seed falling on good soil refers to someone who hears the word and understands it. This is the one who produces a crop, yielding a hundred, sixty or thirty times what was sown.”
24 Jesus told them another parable: “The kingdom of heaven is like a man who sowed good seed in his field. 25 But while everyone was sleeping, his enemy came and sowed weeds among the wheat, and went away. 26 When the wheat sprouted and formed heads, then the weeds also appeared.
27 “The owner’s servants came to him and said, ‘Sir, didn’t you sow good seed in your field? Where then did the weeds come from?’
28 “‘An enemy did this,’ he replied.
“The servants asked him, ‘Do you want us to go and pull them up?’
29 “‘No,’ he answered, ‘because while you are pulling the weeds, you may uproot the wheat with them. 30 Let both grow together until the harvest. At that time I will tell the harvesters: First collect the weeds and tie them in bundles to be burned; then gather the wheat and bring it into my barn.’”
Heb. 10:11 Day after day every priest stands and performs his religious duties; again and again he offers the same sacrifices, which can never take away sins. 12 But when this priest had offered for all time one sacrifice for sins, he sat down at the right hand of God, 13 and since that time he waits for his enemies to be made his footstool. 14 For by one sacrifice he has made perfect forever those who are being made holy.
Clearly the above was written not to Born Again believers, but to Jews who were under the Law. (We don't bother with PRIESTS because we have pastors or shepherds who lead the flock of God. Priests are intermediaries between God and human beings. When Jesus died the "middle wall of partition" was ripped open from top to bottom by the Holy Spirit, opening the way for mankind to reach God sans intermediary priests).
16 “This is the covenant I will make with them
after that time, says the Lord.
I will put my laws in their hearts,
and I will write them on their minds.”[b]
The above is NOT for now definitely. It is for the MILLENNIAL Kingdom when Jesus rules from Jerusalem for a thousand years. The PROMISE is that God will put HIS LAWS in the hearts of the Millennial subjects under Jesus Christ. If the above promise is for now, how come it is NOT happening in our time?
In the Millennial Kingdom there will be no more SACRIFICE for Sins. Sacrifice for sins is OT law. Those who enter the millennial Kingdom get in to it, because their sins have been totally forgiven.
Producing branches are PRUNED for higher production. They are never cut off and thrown in the fire!
