Many people attend the house of God attired the same way they would dress for a rodeo or a football game.
When people are to be guests at the White House for a meeting with the President, they dress up—suits and ties for the men; pretty dresses for the ladies. Appropriate dress indicates appropriate respect. When the President speaks to a joint session of congress, the gallery guests as well as the lawmakers are all dressed in their best. (Dr. Tassell)
I don't know Dr. Tassell "from Adam" (as some of us say)! I DO tend to think these words of his have merit. And he has said it better than I can. I know there are many opinions on this subject..and I know it may be a little too "King Jamesish" for many...but here are more words from a post of his:
I know the Lord looks on the heart, and clothes don't necessarily make the man, but how we dress when we go to a worship service ought to indicate how much we honor our Lord. We do not have to be fashion models, but we should "dress up" for our Saviour's special day at His special house, the local church. The spirit of what I am saying is captured in the words of Malachi:
"Just as I Am" is an invitation for sinners, not a description of how the saints are to attend a church service. The Prodigal Son came home in rags. As soon as his father accepted him, however, he was dressed in a fine robe; shoes were put on his feet and a ring on his finger. Before Joseph went in to have an audience with Pharaoh, "he shaved himself, and changed his raiment" (Genesis 41:14). So should we look our best when going to the house of God to worship the Lord of the Church.
I am not pleading for barring anyone from a church service because of the way he or she is dressed.
Let's not allow our local churches to become sanctuaries of the sloppy and temples of the tacky. Let's respect our Master, minister and message.
God's Holy and Special Person requires reverence on the part of those who know Him and who seek to honor His Name. "God is greatly to be feared in the assembly of the saints, and to be had in reverence of all them that are about Him" (Psalm 89:7). He is the great and awe-inspiring God who demands our worshipful respect, not only in the way we dress, but also in the way we sing.
We dress in a proper and special way on the Lord's Day because it is a special occasion and we are meeting with a special Person, even the God who is to be feared and revered. Because of this special occasion and special Person, we want to sing in a manner that is appropriate and befitting such a worthy and glorious God. It is a time of worship, not entertainment.
The dressing, the singing, the bending of the heart before God in humble worship—all of this is but the preparation of one's heart attitude for the glad reception of God's Holy Word. The One who is high and holy is looking for those who will tremble at His Word (Isaiah 66:1-2). He is looking for those who will bow before the authority of His Word. "Speak Lord, for Thy servant is listening."
