Psa 51:17 The sacrifices of God are a broken spirit; a broken and a contrite heart, O God, You will not despise.
And we know why he saved them. He saved them because they had a contrite spirit or that they chose humility. Notice he didn't impart in them contrition and humility AND THEN he saved them. They chose to have humility towards God's word and salvation followed!
God can't put in one actual humility. God can humble his people BUT that IS NOT humility. Deuteronomy 8:3 says God humbled them, and suffered them to hunger, and fed them with manna, which thou knewest not, neither did thy fathers know; that he might make thee know that man doth not live by bread only, but by every word that proceedeth out of the mouth of the LORD doth man live." However that didn't mean they had humility! They could still get offended in pride and complain and murmur to God and begin to worship other gods which they did most of the time and that certainly wasn't humility.
Calvinism says God saves those that he just chooses too. Good to know the way in which his choice is made....do they choose to walk in humility? Do they receive Jesus as their Lord and King and be glad that they've done so! James says that God resists the proud so if he resists them how can he saved them? Impossible! He does NOT put humility in them. He does not put humility in any one! In James 4:6 we read God resists the proud BUT...he gives his GRACE unto the ones that have humility. There's no indication there that God put anything in them relative to salvation at all! Why? Because they have pride. When Jesus was on the cross the two on each side of him....one chose humility and asked for God's mercy and Jesus said he'd be with him now in paradise....the other not. Lk 23:43 God is merely observing and watching what type of spirit the chose ,THEY CHOSE to have.
In Luke 18:19 we read, "Two men went up into the temple to pray; the one a Pharisee, and the other a publican. The Pharisee stood and prayed thus with himself, God, I thank thee, that I am not as other men are, extortioners, unjust, adulterers, or even as this publican. I fast twice in the week, I give tithes of all that I possess.(in other words he walked in pride) And the publican, standing afar off, would not lift up so much as his eyes unto heaven, but smote upon his breast, saying, God be merciful to me a sinner."(he embraced humility) "I tell you, this man went down to his house justified rather than the other: for every one that exalteth himself shall be abased; and he that humbleth himself shall be exalted."
Notice NO INDICATION God imparted humility or pride in either. God merely observed and responded to whatever spirit THEY CHOSE to have. To actually say God puts humility in one which we would say would be a type of blessing is however to say God would do something he's already said he doesn't do! HE GIVE HIS GRACE....TO.....THE ONE WHO CHOOSES HUMILITY. Not to the ones which haven't. This would mean what Calvinists call their doctrines of Grace aren't actually in truth the doctrines of Grace for grace doesn't work in the way in which they think. That's not to say many Calvinists aren't saved but many things they think about GRACE need to be adjusted.
