To worship God in the beauty of holiness is to worship him in a spiritual way of worship. During the time of old, the Israelites offered living things like goats, sheep, ram etc as their offering to God. In our time, we don't need to offer animals as sacrifice to God, instead we are to offer ourselves as a living sacrifice to God.
Now the question is "how do we offer ourselves as a living sacrifice to God?"
By offering ourselves as a living sacrifice to God, we must live a holy life and worship him in spiritual way. Holiness means being separated from sin and dedicated to God. It's not achieved by human effort alone but by following God's teachings and commandments.
The beauty of holiness is the kind of life that glorifies God, a life filled with righteousness, good works and pure heart. As christians, for us to present ourselves as a living sacrifice to God we must be renewed and holy. Let's always live a holy and righteous life in order to worship God in spiritual way of worship.
God bless you all 🙏.
