Has salvation/justification earned through faith in the sacrifice of our Lord Jesus Christ on the cross made Christianity a cheesy, entertaining religion of automatic entitlement to personal desires? No *1.
Christianity is not mainly entertainment, praise and worship services in the name of feeling good or reaching out to other (these are necessary too) but, we need to be transformed by the renewing of our mind after our initial encounter with God *2, by fervently studying the word, praying and representing our saviour in words, thoughts and deeds. The word of God is powerful, tearing asunder the hearts of men, transforming souls *3. He puts in us both to will and do his good pleasure *4. We only need to submit to the Holy Spirit within us.
The letter below may be a simple act of love but, anything done in the name of our Lord is lifting him up in worship.
