Lab testing is often associated with medical breakthroughs, food safety, environmental monitoring, and product development. At the same time, some forms of testing—particularly those involving animals or environmentally harmful chemicals—raise important ethical concerns. Christians should therefore avoid simplistic answers. Instead of asking whether lab testing is inherently good or bad, we should ask: Does this form of testing help us love God, love our neighbours, and care faithfully for God's creation?
Laboratory testing touches nearly every aspect of modern life. But how Christians approach lab testing reflects a broader question: How should scientific knowledge be used in God's world? Creation care calls Christians not only to appreciate creation but also to pursue knowledge that promotes creation’s flourishing.
One assumption behind the question is that science and Christian faith may be in conflict. Scripture, however, presents creation as orderly because it is created by an orderly God. Studying creation is therefore not opposed to our faith and can be an act of faithful stewardship given that God’s heart for creation remains at the centre of it.
Another assumption is that scientific progress automatically justifies every method used to achieve it. The Bible challenges this idea. While human beings are called to cultivate and develop creation, our authority is never absolute, in that our Creator is the one who holds it all.
The biblical story begins with humanity's vocation:
"The LORD God took the man and put him in the garden of Eden to work it and keep it." (Genesis 2:15, ESV)
The Hebrew verbs suggest both cultivating and guarding creation. Scientific investigation—including laboratory work—can be one way of fulfilling this responsibility by helping us understand diseases, ecosystems, agriculture, and environmental changes.
Psalm 111:2 (ESV) also celebrates careful study:
"Great are the works of the LORD; studied by all who delight in them."
Studying God's creation is an act of worship because we then delight in God’s creation and glorify Him.
Scripture also teaches compassion toward animals. Proverbs 12:10 (ESV) says:
"Whoever is righteous has regard for the life of his beast, but the mercy of the wicked is cruel."
Despite humans being given dominion over animals in biblical theology, animals are still God’s creatures with intrinsic value. Human beings alone bear God's image (Genesis 1:26–28, ESV) but God made animals and delight in them (Psalm 104, ESV) and Christians should therefore not treat animals as disposable research tools.
Jesus summarises God's law as loving God and loving our neighbour (Matthew 22:37–39, ESV). Lab testing in the medical and environmental sense are definitely also ways for Christians to live out these laws.
Medical diagnostic testing that helps identify illnesses, improve treatments, and protect public health aligns well with the biblical call to heal and care for others. Developing such life-saving treatments can be an expression of our love for our neighbours.
Environmental laboratory testing—including testing air quality, water quality, soil contamination, and biodiversity—is deeply consistent with creation care. These tools help us identify ecological damage and make wiser decisions about protecting God's creation, for instance: vulnerable communities who are often disproportionately affected by environmental degradation.
Animal testing presents a more complex ethical issue, and deserves great scrutiny especially so in the case of consumer products such as cosmetics. Christians should support efforts to minimise animal suffering and encourage the development of alternatives wherever possible despite some biomedical research with animal testing which have contributed significantly to treatments for serious diseases. Many researchers today follow the internationally recognised 3Rs framework: Replacement (using non-animal methods when possible), Reduction (using fewer animals), and Refinement (improving methods to minimise suffering). These principles resonate with the biblical themes of responsible dominion and compassion.
Christians should then also consider the environmental footprint of laboratories themselves. Scientific institutions consume significant amounts of energy, water, plastics, and hazardous chemicals. Faithful stewardship includes encouraging more sustainable laboratory practices without compromising safety or scientific integrity. As individuals, Christians can choose to support companies with ethical certifications or even advocate for corporate transparency of their testing and laboratory policies.
Creation care reminds us that knowledge is never an end in itself. God gives humanity the ability to investigate creation so that we may serve His purposes of life, justice, healing, and flourishing. Laboratory testing becomes faithful stewardship when it protects human health, preserves ecosystems, advances knowledge, and respects the creatures God has made.
Christians need not fear science. Rather, we are called to ensure that science is practised with wisdom, humility, compassion, and reverence for the Creator. Faithful discipleship means asking not only, "Can we do this?" but also, "Should we?" and "Does this reflect God's love for both people and the rest of creation?"
Thank you for letting us know.
