In Matthew 5:38-42 Jesus tells us,
“You have heard that it was said, ‘Eye for eye, and tooth for tooth.' But I tell you, do not resist an evil person. If anyone slaps you on the right cheek, turn to them the other cheek also. And if anyone wants to sue you and take your shirt, hand over your coat as well. If anyone forces you to go one mile, go with them two miles. Give to the one who asks you, and do not turn away from the one who wants to borrow from you."
Psalm 50:10-11 tells us that,
"for every animal of the forest is mine, and the cattle on a thousand hills. I know every bird in the mountains, and the insects in the fields are mine."
EVERYTHING that you or I 'own' is, in reality, nothing but a 'loan' from God. NOTHING is ours, it is all HIS! Trying to keep His possessions if He does not will it, is not wise and will fail spectacularly! If He decides to let you 'keep' whatever possessions, praise God! If He decides to take His possessions and 'loan' them to someone else, praise God! Job was a very wealthy and righteous man, yet God allowed satan to take EVERYTHING from him. He ended up living at the dump, using broken pottery shards to scrape the pus out of his wounds! He could do NOTHING to prevent this from happening.
God does not give us gifts because we are entitled to them, He gives us possessions because He CHOOSES to. What we 'have' is to be used for His glory, not for ours. If Jesus was able to feed 5,000 men, plus their kids and women folk with five loaves and two fish, don't you think He can provide for whom He chooses? Likewise, in Exodus 16, we know that those who greedily gathered too much manna, for the next day, found it smelling and full of maggots in the morning.
God wants us to depend on Him, not ourselves! Mark 10:13-16 tells of Jesus rebuking the disciples for chasing little children away.
"People were bringing little children to Jesus for him to place his hands on them, but the disciples rebuked them. When Jesus saw this, he was indignant. He said to them, “Let the little children come to me, and do not hinder them, for the kingdom of God belongs to such as these. Truly I tell you, anyone who will not receive the kingdom of God like a little child will never enter it.” And he took the children in his arms, placed his hands on them and blessed them. .
Why are we to be 'child-like'? A child is innocent (as opposed to sinless), MOSTLY obeys his/her parents and DEPENDENDS upon their parents, NOT themselves! THAT is what Jesus wants from us! Planning for survival when the SHTF, independent from God, is PURE FOLLY! When the SHTF is when we ABSOLUTELY MUST depend on God over ourselves!
No matter how you prepare, if He doesn't CHOOSE to let you keep something, you ain't gonna keep it. Maybe the gospel of Chris! tells you something different, but I'll choose to believe the Word of Jesus, the Christ!
