This easy to read book explains how worship is so much more than what we typically assume it to be (for example, the singing of hymns and praise choruses together, which may or may not actually involve true worship). We must first understand the concept of God’s intrinsic and eternal glory, all of the aspects of God’s character that make him worthy of our utmost praise and adoration. The author spends several chapters making the case for who God is and why we should worship Him. Jesus says that the Father must be worshiped in spirit and in truth (John 4:24). Simply stated, God is pleased when our hearts are sincere in His presence and our minds are renewed by the truth of His Word. MacArthur stresses the fundamental requirements of salvation and sanctification for God to accept our worship, which is to say that we must wholeheartedly believe God’s testimony as revealed in the Bible and be growing in faith and holiness in order to offer acceptable worship. Praising the Lord is not supposed to be confined to Sunday morning church service but rather the overflow of a life devoted to Him, as His glory far outweighs everything else whether good or bad. While this book presents an extremely high standard for approaching God, it is also vitally noted that we may come into His presence only by His mercy and grace. We are divinely enabled to glorify God in the way commanded, yet obviously impossible apart from the work of the Holy Spirit within us.
