There are two grand vital points that every Christian should seek to be established in. The first is,—Is he a believer in Christ? Has the blessed Spirit made Christ known to his soul? Has he embraced Jesus in the arms of living faith? The second point which he should seek to have established in his soul is,—Does he abide in Christ? This he may know by having some testimony that Christ abides in him, and produces the fruits that flow out of this inward abiding. If Christ abide in him, his heart will not be like the nether mill-stone. He cannot rush greedily into sin; he will not love the world, and the things of time and sense; he cannot happily love idols, or do those things which ungodly professors do without one check or pang.
Jesus in the soul is a guest that will make himself known; yea, abiding there, he is King therein. He is Ruler in Zion, and when he comes into the heart, he comes as King. Being, therefore, its rightful Sovereign, he sways the faculties of the soul, and makes it obedient to his sceptre; for "thy people shall be willing in the day of thy power" (Psalm 110:3). "O Lord our God, other lords beside thee have had dominion over us; but by thee only will we make mention of thy name" (Isaiah 26:13)
