The peace of Christ is not a boisterous, untamable element made manifest in loud voices and bodily exercises. The peace of Christ is an intelligent peace, and it does not make those who possess it bear the marks of fanaticism and extravagance. It is not a rambling impulse but an emanation from God. FW 87.4
When the Saviour imparts His peace to the soul, the heart will be in perfect harmony with the Word of God, for the Spirit and the Word agree. The Lord honors His Word in all His dealings with men. It is His own will, His own voice, that is revealed to men, and He has no new will, no new truth, aside from His Word, to unfold to His children. If you have a wonderful experience that is not in harmony with expressed directions of God's Word, you may well doubt it, for its origin is not from above. The peace of Christ comes through the knowledge of Jesus whom the Bible reveals. FW 88.1
If happiness is drawn from outside sources and not from the Divine Fount, it will be as changeable as varying circumstances can make it; but the peace of Christ is a constant and abiding peace. It does not depend on any circumstance in life, on the amount of worldly goods, or the number of earthly friends. Christ is the fountain of living waters, and happiness and peace drawn from Him will never fail, for He is a well-spring of life. Those who trust in Him can say: “God is our refuge and strength, a very present help in trouble. Therefore will not we fear, though the earth be removed, and though the mountains be carried into the midst of the sea; though the waters thereof roar and be troubled, though the mountains shake with the swelling thereof.... There is a river, the streams whereof shall make glad the city of God, the holy place of the tabernacles of the Most High” (Psalm 46:1-4). FW 88.2
We have reason for ceaseless gratitude to God that Christ, by His perfect obedience, has won back the heaven that Adam lost through disobedience. Adam sinned, and the children of Adam share his guilt and its consequences; but Jesus bore the guilt of Adam, and all the children of Adam that will flee to Christ, the second Adam, may escape the penalty of transgression. Jesus regained heaven for man by bearing the test that Adam failed to endure; for He obeyed the law perfectly, and all who have a right conception of the plan of redemption will see that they cannot be saved while in transgression of God's holy precepts. They must cease to transgress the law and lay hold on the promises of God that are available for us through the merits of Christ. FW 88.3
