lose the technical jargon

'Tim Keller: [Worship] language should be free from technical jargon, and especially evangelical subculture terminology. There are innumerable phrases that we fall back on because they sound “spiritual,” but they are sentimental and undecipherable for non-initiates. For example: “Let us come unto the Lord.” “Let us just lift up the name of Jesus.” “We pray for a hedge of protection around him, Lord.” Overuse of the word blessing is another example of jargon. Key theological terms like justification can be introduced and explained. Subcultural talk, however, is at best highly exclusionary and at worst very phony, a ruse to hide a lack of actual heart engagement.'
