This is the concept that there are two equally powerful entities in the spiritual world. While there are two forces, God, representing good, is vastly superior and more powerful than Satan who represents evil. Satan never was
and never will be an opposite or equal to God. God Almighty, is the most powerful force in the universe without

God has no equal

exception. Satan, was a created angel before he rebelled and is under God's control and in the future will be exiled to his appointed place of eternal damnation (Isa 14:12-15; Ezek 28:13-17; Mt 25:41). The Scriptures state, "the one who is in you [Holy Spirit] is greater than the one [Satan and his evil forces] who is in the world" (1 Jn 4:4). God is omnipresent (present everywhere at once), omnipotent (all powerful), omniscient (all knowing), and sovereign over all. Satan has none of these capabilities.

Dualism has also been applied to the concept of separating the spiritual from the secular in our culture by compartmentalising different aspects of life instead of all being part of the whole but this is not in keeping with biblical teaching. We may think ‘full time’ Christian work is more spiritual and so be discontented and dissatisfied in life if we are not in such ministry. However, we are to be ‘full time’ for the Lord whatever our occupation. God is to be found in work as well as in prayer. Spiritual reality should include everyday life, and enhance our whole lifestyle, not be separate or unrelated from it.

Rediscovering the presence of God in everyday life results in more rewarding, increased productivity and a less stressed life lived in connection with God. He wants to be included in our daily activity. Authentic Christianity is living in vital consistent relationship to the source of real life, who is everywhere (omnipresent) if we can but comprehend Him (Jn 10:10).

Poverty, the environment, justice, economics, politics, work and professional life are the issues that occupy the attention of our society. Generally the Christian church, because it has focused almost exclusively on the ‘spiritual’ disciplines (worship, prayer, etc), has largely lost its relevance and ability to connect with and impact the unsaved world.  Christ should be part of our whole existence. Through

our concern and efforts in the ‘secular’ world, we can be salt and light, influencing and bringing about change in the areas that need addressing while all the time sowing seeds for the Kingdom (Mt 5:14-16).
