Why is it important for Christians to wear spiritual armor?

Spiritual armor is vital for Christians because it provides protection in a life characterized as a battleground against sin and Satan. The Apostle Paul highlights the reality that we are engaged in constant spiritual warfare, facing internal conflicts stemming from our sinful nature, external pressures from the world, and direct opposition from Satan. By putting on the full armor of God, believers can effectively resist these threats and remain steadfast in their commitment to follow Christ, knowing that their provision and protection come from God Himself.
