Short-term and long-term memory work together as the twin pillars of human cognition, each serving a vital yet distinct purpose in how we understand and interact with the world. William James (1890) first distinguished between primary (short-term) and secondary (long-term) memory, laying the foundation for modern theories of memory systems. Decades later, George Miller (1956) demonstrated the limited capacity of short-term memory, famously identifying the “magical number seven, plus or minus two”, while Atkinson and Shiffrin (1968) proposed a landmark multi-store model describing how information moves from sensory input to short-term and then to long-term storage. Later, Alan Baddeley and Graham Hitch (1974) refined our understanding through the working memory model, emphasizing how active processing, not just storage, supports thought and comprehension. Short-term memory acts like a mental notepad, holding small amounts of information briefly to help us focus on the present, while long-term memory serves as a vast and enduring archive of knowledge, experiences, and identity. Together, they form the foundation of learning, creativity, and resilience. For personal wellbeing, this balance allows growth, reflection, and emotional stability; for society, the shared strength of memory, preserved through education, culture, and history, fuels empathy, innovation, and the progress of civilisation itself. How we use memory is important. When the powerful mechanisms of short- and long-term memory are used under the guidance and inspiration of the Holy Spirit, the benefit to the individual, their society, and the Kingdom of God, is maximised. In the words of Jesus Christ, a person so instructed is someone who “brings out of his treasure things new and old” (Matthew 13:52).
