Redeeming for God? i don't think any Christian who celebrates it is trying to redeem it for God, but they can however decide how they will celebrate it and I choose to be with God while handing out candy for the kids.
But please do show the scripture that speaks on how to not celebrate halloween I have searched but could not find it regarding Halloween itself or Christmas for that matter just lots of people using scripture that sort of fits the bill but not really
There are Scriptures that speak to those holidays in particular. But there are numerous teaching that you shouldn't have anything to do with pagan customs and traditions.
Deuteronomy 12:29-31 “When the Lord your God cuts off before you the nations which you are going in to dispossess, and you dispossess them and dwell in their land,
30 beware that you are not ensnared to follow them, after they are destroyed before you, and that you do not inquire after their gods, saying, ‘How do these nations serve their gods, that I also may do likewise?’
31 You shall not behave thus toward the Lord your God, for every abominable act which the Lord hates they have done for their gods; for they even burn their sons and daughters in the fire to their gods."
Deuteronomy 18:9 “When you enter the land which the Lord your God gives you, you shall not learn to imitate the detestable things of those nations”.
Jeremiah 10:1-5 “Hear the word which the Lord speaks to you, O house of Israel.
2 Thus says the Lord,”
“Do not learn the way of the nations,
And do not be terrified by the signs of the heavens
Although the nations are terrified by them;
3 For the customs of the peoples are a delusion;
Because it is wood cut from the forest,
The work of the hands of a craftsman with a cutting tool.
4 “They decorate
it with silver and with gold;
They fasten it with nails and with hammers
So that it will not totter.
5 “Like a scarecrow in a cucumber field are they,
And they cannot speak;
They must be carried,
Because they cannot walk!
Do not fear them,
For they can do no harm,
Nor can they do any good.”
Romans 12:2 “Do not conform any longer to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God's will is--his good, pleasing and perfect will.”
2 Corinthians 6:16 “What agreement is there between the temple of God and idols? For we are the temple of the living God. As God has said: "I will live with them and walk among them, and I will be their God, and they will be my people." 17 "Therefore come out from them and be separate, says the Lord. Touch no unclean thing, and I will receive you."
Colossians 2:8 "See to it that no one takes you captive through philosophy and empty deception, according to the tradition of men, according to the elementary principles of the world, rather than according to Christ."
In addition, how many times did God tell His people to destroy the High Places of the nations they inhabited? What happened to them when they didn't?
