How gift giving works.
For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:  Not of works, lest any man should boast.  For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them. Ephesians 2:8-10 God does not take back the gift of salvation that He freely offers. So He is not an "Indian giver" as some claim that others believe incorrectly. For the gifts and calling of God are without repentance. Romans 11:29 Every good gift and every perfect gift is from above, and cometh down from the Father of lights, with whom is no variableness, neither shadow of turning. James 1:17 While God will not take back the gift those who receive the gift can certainly and sadly reject it later on and return to their sin. For if after they have escaped the pollutions of the world through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning.  For it had been better for them not to have known the way of righteousness, than, after they have known it, to turn from the holy commandment delivered unto them.  But it is happened unto them according to the true proverb, The dog is turned to his own vomit again; and the sow that was washed to her wallowing in the mire. 2 Peter 2:20-22 It is not the gift giver who will ever walk away but the gift receiver certainly can. A gift can be freely accepted or rejected during any part of the process. Take heed, brethren, lest there be in any of you an evil heart of unbelief, in departing from the living God. Hebrews 3:12 So good gifts, especially the gift of salvation, should be diligently maintained with reverence. It is a biblical fact demonstrated by God's warnings in His Word that this gift can be rejected either immediately or later on after receiving the gift. If anyone demands otherwise then it is not a gift per their own warped definition. Grace and peace be multiplied unto you through the knowledge of God, and of Jesus our Lord,  According as his divine power hath given unto us all things that pertain unto life and godliness, through the knowledge of him that hath called us to glory and virtue:  Whereby are given unto us exceeding great and precious promises: that by these ye might be partakers of the divine nature, having escaped the corruption that is in the world through lust.  And beside this, giving all diligence, add to your faith virtue; and to virtue knowledge;  And to knowledge temperance; and to temperance patience; and to patience godliness;  And to godliness brotherly kindness; and to brotherly kindness charity.  For if these things be in you, and abound, they make you that ye shall neither be barren nor unfruitful in the knowledge of our Lord Jesus Christ.  But he that lacketh these things is blind, and cannot see afar off, and hath forgotten that he was purged from his old sins.  Wherefore the rather, brethren, give diligence to make your calling and election sure: for if ye do these things, ye shall never fall:  For so an entrance shall be ministered unto you abundantly into the everlasting kingdom of our Lord and Saviour Jesus Christ. 2 Peter 1:2-11 Wherefore, my beloved, as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling. Philippians 2:12 And ye shall be hated of all men for my name's sake: but he that endureth to the end shall be saved. Matthew 10:22 And being made perfect, he became the author of eternal salvation unto all them that obey him; Hebrews 5:9 He that overcometh shall inherit all things; and I will be his God, and he shall be my son. Revelation 21:7 Bith giving and receiving gifts infer that free will is in play. Heal the sick, cleanse the lepers, raise the dead, cast out devils: freely ye have received, freely give. Matthew 10:8 Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God. 1 Corinthians 2:12 I will freely sacrifice unto thee: I will praise thy name, O Lord ; for it is good. Psalm 54:6 That is how gifts work.
