Satan is now more earnestly engaged in playing the game of life for souls than at any previous time; and unless we are constantly on our guard, he will establish in our hearts, pride, love of self, love of the world, and many other evil traits. He will also use every possible device to unsettle our faith in God and in the truths of His Word. If we have not a deep experience in the things of God, if we have not a thorough knowledge of His Word, we shall be beguiled to our ruin by the errors and sophistries of the enemy. False doctrines will sap the foundations of man, because they have not learned to discern truth from error. Our only safeguard against the wiles of Satan is to study the Scriptures diligently, to have an intelligent understanding of the reasons of our faith, and faithfully to perform every known duty. The indulgence of one known sin will cause weakness and darkness and subject us to fierce temptation....
Are our supplications ascending to God in living faith? Are we opening the door of the heart to Jesus and closing every means of entrance to Satan? Are we daily obtaining clearer light and greater strength, that we may stand in Christ’s righteousness? Are we emptying our hearts of all selfishness, and cleansing them, preparatory to receiving the latter rain from heaven?
Now is the time when we are to confess and forsake our sins, that they may go beforehand to judgment and be blotted out. Now is the time to “cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God” (2 Corinthians 7:1). It is dangerous to delay this work. Satan is even now seeking by disasters upon sea and land to seal the fate of as many as possible. What is the defense of the people of God at this time? It is a living connection with heaven. If we would dwell in safety from the noisome pestilence, if we would be preserved from dangers seen and unseen, we must hide in God; we must secure the protecting care of Jesus and holy angels. HP 348
It is very necessary that we should pray in order that we may have strength from above to see and resist the temptations of the enemy; but Satan ever seeks to prevent men from praying, by filling up their time with business or pleasure, or by leading them into such wickedness that they will have no desire to pray. Pr 241-242
"Because thou hast kept the word of my patience, I also will keep thee from the hour of temptation, which shall come upon all the world, to try them that dwell upon the earth." Revelation 3:10 (King James Version)
