One huge battle every Christian faces, is the temptation to compromise Bible doctrine (teaching). In the Book of Revelation Chapters 2 & 3 Jesus rebukes the churches because they had compromised and left their first love. They had compromised and allowed the doctrines of the Nicolaitans to infiltrate the church. They had embraced the doctrine of Balaam. They allowed that woman Jezebel, who called herself a prophetess, to influence the church. It is because of these kinds of compromises that the influence of Christians in the world has been weakened (Acts 16). The Bible asks; “what communion has light with darkness?” (2 Cor.6:14) But the enemy always attempts to combine them. Today, there is a movement toward ecumenism (unity). Its supporters say we need to put aside the differences in our doctrine so that we can all be united. Christians cannot do that. Christians must maintain doctrinal purity and refuse to compromise in order to have victory in the Spiritual battles.
