We are told in many ways that the only things that are important are the physical: what we can see, hear, taste and touch. Anything else is either non-existent or unimportant. When we choose to follow Christ, our eyes become open to another reality. We find out that there is an unseen world where God dwells as well as our enemy. Pastor Mark is teaching that when we become servants of God we’re automatically enlisted in a war with forces unseen but effective. We’ll be learning exactly who our opposition is and how to live our lives in such a way that we can be victorious over them.
