Jesus expects all who claim to be His soldiers to do service for Him. He expects you to recognize the enemy and to resist him, not to invite him to your confidence and thus betray sacred trust. The Lord has placed you in a position where you may be elevated and ennobled, and be constantly gaining fitness for His work. If you do not obtain these qualifications; you alone are to blame.
There are three ways in which the Lord reveals His will to us, to guide us, and to fit us to guide others. How may we know His voice from that of a stranger? How shall we distinguish it from the voice of a false shepherd? God reveals His will to us in His Word, the Holy Scriptures. His voice is also revealed in His providential workings; and it will be recognized if we do not separate our souls from Him by walking in our own ways, doing according to our own wills, and following the promptings of an unsanctified heart, until the senses have become so confused that eternal things are not discerned, and the voice of Satan is so disguised that it is accepted as the voice of God.
Another way in which God's voice is heard is through the appeals of His Holy Spirit, making impressions upon the heart, which will be wrought out in the character. If you are in doubt upon any subject, you must first consult the Scriptures. If you have truly begun the life of faith, you have given yourself to the Lord to be wholly His, and He has taken you to mold and fashion according to His purpose, that you may be a vessel unto honor. You should have an earnest desire to be pliable in His hands and to follow whithersoever He may lead you. You are then trusting him to work out His designs, while at the same time you are cooperating with Him by working out your own salvation with fear and trembling. You, my brother, will find difficulty here because you have not yet learned by experience to know the voice of the Good Shepherd, and this places you in doubt and peril. You ought to be able to distinguish His voice.--Testimonies, vol. 5, pp. 511, 512. YRP 102
The most valuable teaching of the Bible is not to be gained by occasional or disconnected study. Its great system of truth is not so presented as to be discerned by the hasty or careless reader. Many of its treasures lie far beneath the surface, and can be obtained only by diligent research and continuous effort. ED 123
