What is the meaning of the two candles and one candle in wedding ceremonies?
In wedding ceremonies, the two candles represent the husband and wife as two separate people, and the single candle represents their becoming one in marriage, which pictures the same oneness that believers enjoy with Christ as members of His body.
Les explains from Ephesians 5:25 that Paul addresses the husband's responsibility in marriage, showing that Christ's relationship to believers is identical to the husband-wife relationship. A marriage made in heaven involves two people becoming one, and many wedding ceremonies picture this by blowing out two candles and lighting one. Les says that is exactly what it is supposed to be. In the same way, believers are two separate entities, but once in union with Christ they become one with Him, just like husband and wife. This is a deep spiritual concept comprehended only by faith, and Scripture teaches it, so we must believe it. Les also references Deuteronomy 29:29, that secret things belong to the Lord, but once revealed they belong to us and our children, because God is revealing a relationship between Christ and believers as members of His body.
