Satan has summoned the hosts of darkness to war against the saints. We cannot afford to be indifferent to his attacks. He comes in many ways, and we must have clear spiritual discernment, that we may be able to discern when he is seeking to gain possession of our minds. God calls on those on whom the light of truth is shining to take their stand in His army. He calls upon them to show their loyalty by walking in the light He has given. (OHC 19.4) MC VC

When he [Satan] suggests doubts as to whether we are really the people whom God is leading, whom by tests and provings He is preparing to stand in the great day, be ready to meet his insinuations by presenting the clear evidence from the Word of God that this is the remnant people who are keeping the commandments of God and the faith of Jesus. (OHC 85.4) MC VC

There is a class who say, “I believe, I believe,” and lay claim to all the promises which are given on condition of obedience; but they do not the works of Christ. God is not honored by any such faith. It is spurious. Another class are trying to keep all the commandments of God, but many of them do not come up to their exalted privilege in claiming the promises that were given for them. God’s promises are for those who keep His commandments, and do those things that are pleasing in His sight. (OHC 119.4) MC VC
