We know we were represented by Adam because we are born sinners, spiritually dead in trespasses and sins.
The connection to Adam is evident through our innate sinful nature. Romans 5:12 states, 'wherefore as by one man sin entered into the world, and death by sin.' The experience of sinfulness is a crucial indicator of our representation by Adam. We are all born with a sinful nature, and our actions affirm that we are sinners, confirming that we share in Adam’s fall. The scripture clearly states that death passed upon all men for that all have sinned, which signifies our linkage to Adam's disobedience, resulting in spiritual death and separation from God. Therefore, anyone wondering about their connection to Adam can consider their own sinfulness as evidence of that representation.
