It seems that every aspect of our lives have become more casual, from our work, to our dress, to our worship. Somewhere along the line, the importance of God and the relevance of His Church has diminished. If one examines the 25th chapter of Exodus, where the instructions and construction of the tabernacle is described, you will find that casual is not present. First of all, the people gave an offering, not of convenience, but of sacrifice and most importantly, from a willing and grateful heart. The offering (or building fund) consisted of gold, silver, bronze, fine linen, onyx stones, and stones to be set in the breastplate of the high priest. The people gave their very best, not their leftovers, because their relationship with God was the most important relationship in their lives.
One thing has not changed. Regardless of the opinion of society, the most important relationship that a person will have is the relationship they have with their Creator. Have a blessed day.
