CELEBRATIONS

Some of the more conservative Christian groups view parties and celebrations as unnecessary temptations that are better off avoided. Is this what the bible teaches?

No.

It is not sinful to participate in celebrations, as we read that the bible is supportive of celebrations (Ecclesiastes 3:12-13, Ecclesiastes 8:15). For example:
1-- God invented weddings (Genesis 2:21-25) and wedding celebrations are perfectly acceptable (Genesis 29:27, John 2:1-2).
2-- God blessed humans with the ability to procreate (Genesis 1:28, 9:1), and children are a joyous gift from God (Exodus 1:21, Psalms 113:9, Psalms 127:3). Therefore, celebrating one's children is a good thing (Genesis 21:8, Deuteronomy 26:11, Psalms 113:9, Luke 15:20-24).
3-- The coronation of kings chosen by Yahweh was considered a celebratory event (1 Samuel 11:15, 1 Kings 1:38-40).
4-- Godly victories were celebrated (1 Samuel 18:6-7, 2 Samuel 6:14-19).
5-- The rebuilding of the Temple was celebrated (Ezra 3:10-13).
6-- Rescue from genocide was also celebrated (Esther 8:15-17).
7-- Entertaining guests was an acceptable form of recreation (Luke 19:1-6, Acts 2:46).
And the list goes on and on. The bible shows us that rejoicing and celebration are acceptable parts of every day living (Leviticus 23:40, Deuteronomy 12:7).

Celebrations are to be joyous events. They can include music and dancing (Judges 11:34, 2 Samuel 6:5, Psalms 149:3), and plenty of food (Genesis 21:8, 29:22). We must keep in mind, though, that all things should be in moderation. In other words, we should be careful that we don't overeat or drink too much (Proverbs 23:20, Luke 21:34, 1 Corinthians 6:9-11, Galatians 5:21), and that our musical entertainment doesn't give way to loose conduct and temptations (Mark 7:20-23, Romans 13:13-14, 1 Corinthians 6:18, 1 Corinthians 10:14, 1 Timothy 6:11). We must also beware of entertainment that promotes filthy talk and offensive language (Proverbs 2:10-12, Proverbs 8:13, Ephesians 5:3-5).

The main point is to find balance. As long as all things are done for God's glory (1 Corinthians 10:31), there is no sin in celebrating various events in life. Being a Christian and having fun is very compatible. Looking at the whole picture, we see that we as Christians can have get togethers with friends, enjoy music, rejoice in various celebrations, while keeping our actions clean in front of our God and our Lord.
