Now these things occurred as examples to keep us from setting our hearts on evil things as they did. 7 Do not be idolaters, as some of them were; as it is written: “The people sat down to eat and drink and got up to indulge in revelry.” (I Corinthians 10:6-7)
It is not necessarily sinful to “have a party.” Joy and happiness can be a good thing, as long as we are happy about what is right. Our joy and thanksgiving need to overflow from our appreciation for the love of God. Only when we rejoice in the blessings of God can we be truly, spiritually, contented.
But the Israelites mentioned in the passage above were not “partying” in a way that honored God. They were idolaters who had built a golden calf to take the place of God. They credited this idol with providing for them the blessings that God had given them, and in this spirit of rebelliousness and self-indulgence, they sat down to eat and drink and got up to indulge in revelry. This is clearly wrong, because instead of worshiping God, they were honoring anything that stood against God. This is what we as humans today are guilty of in much of our partying: we rejoice in doing wrong. We worship pleasure in the place of God, because we consider ourselves to be more important than God. But God will someday judge us for this idolatry if we do not repent.
Those who do not worship the one true God have no real love or respect for other humans who were created in God’s image.
