The phrase, “worship God in ceaseless tenacity” came from the Logos Bible Software web site, the book “An Exposition on Prayer in the Bible: Igniting the Fuel to Flame Our Communication with God” ((You can find it here which by its nature as a book pre-publication sale is transitory.)) I was impressed with the way it expressed the truth of three verses from the Bible: Hebrews 13.15, Romans 12.1 and Galatians 5.17
It struck me because I often think of worship as an emotional experience at church or during devotions. You see folks on Christian videos worshiping with their hand held up to God and looks of peace and joy on their faces. That is worship too and maybe even tenacious worship. You never know what it costs a person to seek the Lord at church in that way.
That said, I think that “worship God in ceaseless tenacity” has more to do with devotion to following Jesus all day long than it does with punctual emotional experiences.
Today, as before, those punctual emotional experiences are also an experiential apologetic for Christianity. It is interesting to see a diversity of apologetic approaches. There are four discussed at Bible.org called “Integrating Diverse Arguments in Apologetics”
Hebrews 13.15 “Through Him then, let us continually offer up a sacrifice of praise to God, that is, the fruit of lips that give thanks to His name.”
Romans 12.1 “Therefore, I urge you, brothers, in view of God’s mercy, to offer your bodies as living sacrifices, holy and pleasing to God—this is your spiritual act of worship.”
Galatians 5.17 “For the sinful nature desires what is contrary to the Spirit, and the Spirit what is contrary to the sinful nature. They are in conflict with each other, so that you do not do what you want.”
