RESPECTING GOD'S WORD, GOD'S WORLD, AND PEOPLE IN GOD'S IMAGE

Geology research motivated by the Genesis record

• I believe what God says in the Bible about His creating and sustaining the universe, the world, life, humans, and time.
• I am convinced of the explanatory power of plate tectonics, the geologic column, and radiometric dating and of our need to care for this Earth.
• I trust my good friends in the church community and the science community.
• We respect God's Word, God's world, and people in God's image.
• Our goal is to encourage a supportive relation between Christianity and science and to draw people to Christ.
•  
• Here is the resulting poster project submitted for the Virtual Exhibition of the Seventh-day Adventist world church General Conference Session, June 6-11, 2022.
• It is part of the Geoscience Research Institute contribution and shows our continuing search for harmony as we study God's two books.

• The people of the world are worshiping false gods. They are to be turned from their false worship, not by hearing denunciation of their idols, but by beholding something better. God's goodness is to be made known. "Ye are My witnesses, saith the Lord, that I am God." Isaiah 43:12. (COL299)

Approach: Scripture

• For in six days the Lord made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the Lord blessed the sabbath day, and hallowed it. (Ex 20:11)
• EVIL: "I own that I cannot see as plainly as others do, and as I should wish to do, evidence of design and beneficence on all sides of us. There seems to me too much misery in the world. I cannot persuade myself that a beneficent and omnipotent God would have designedly created the Ichneumonidae with the express intention of their feeding within the living bodies of Caterpillars, or that a cat should play with mice." — Charles Darwin

• an unbeliever's thoughts / 12 February 2014 / Steve Wells -- answers that have been given
• Why Would God Create a World Where Animals Eat Their Offspring? / 22 May 2019 / Fazale Rana / Reasons to Believe
• TIME: And when he had opened the fifth seal, I saw under the altar the souls of them that were slain for the word of God, and for the testimony which they held: And they cried with a loud voice, saying, How long, O Lord, holy and true, dost thou not judge and avenge our blood on them that dwell on the earth? (Rev 6:9-10)

Approach: Harmony

• quotes from Job
• Though he slay me, yet will I trust in him: but I will maintain [margin: prove, or, argue] mine own ways before him. (Job 13:15)
• Then Job answered the Lord, and said, Behold, I am vile; what shall I answer thee? I will lay mine hand upon my mouth (Job 40:3-4)
• Then Job answered the Lord, and said, I know that thou canst do every thing ... I uttered that I understood not; thing to wonderful for me, which I knew not. (Job 42:1-4)
• ARTWORK: Job Confessing his Presumption to God who Answers from the Whirlwind / William Blake
• commentary
• Illustrations of the Book of Job — Wikipedia
• "my ways higher than your ways" (Isa 55:8-11)
• "many things to say ... but cannot bear them now" (Jn 16:12)
• Paul heard unspeakable words in paradise (2Cor 12:4)
• Now we know only in part and eventually even that knowledge will vanish away (1Cor 13:8-9).
• infinite ideas not contained in finite vehicles of thought (1SM22)
• 1000 ways ... "of which we know nothing" (DA330)
• mysteries because of "our own weakness or ignorance" (Ed171)
• His creative power is "incomprehensible" (PP113)

Approach: People

• We draw people to Christ not by loudly discrediting what they believe, by telling them how wrong they are and how right we are, but by showing them a light that is so lovely that they want with all their hearts to know the source of it. — Walking on Water: Reflections on Faith and Art, Madeleine L'Engle (Colorado Springs, CO: WaterBrook Pres, 2004), p.140-141. — reviews: | 1 | 2 |
