With the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. Romans 10:10. LHU 273.1
According to this, there is something to believe, also something to confess. The heart must first accept the truth as it is in Jesus. This is the foundation of true religion. Conviction of sin then begins to be felt; the sin-sick soul, feeling his need of a physician, comes to Jesus of Nazareth for pardon. Taking up the warfare against the enemy, he looks to Jesus for strength to resist temptation. He watches unto prayer, and searches the Scriptures. The truths of the Bible are seen in a new and intensely interesting light, and the Spirit of God opens to him their solemn importance. He studies the life of Christ, and the more clearly he discerns the spotless purity of the Saviour's character, the less confidence he has in his own goodness; the more steadily and closely he views Jesus, the less he discovers of perfection in himself. His self-righteousness disappears, and he falls, all helpless and broken, upon the Rock, Christ Jesus. He will be sorely pressed by the tempter, and at times may have feelings of discouragement, and be tempted to think that God will not accept him; but, taking God at His word, and pleading His sure promises, he presses through the darkness into the clear sunlight of Christ's love. LHU 273.2
“And with the mouth confession is made unto salvation.” If the heart is indeed the treasure house of grace and the love of Christ, these will be expressed in the words and deportment. There will be a constant attraction to Christ. All will be tested; hence the need of divine grace, and of sound religious faith and principles. The lips should be sanctified, that the words spoken may be few and well chosen. LHU 273.3
Oftentimes professed Christians bring upon themselves great spiritual weakness by dwelling upon their trials and grievances. Not only does the matter become magnified by every repetition, but they as surely separate from Jesus as they allow themselves to transgress in this particular. Satan seeks to draw their attention to themselves, and to fasten upon them the idea that they are not appreciated. They begin to pity and sympathize with themselves, and to lose faith and confidence in Jesus; and as the result they walk apart from Him who asks them to cast their burdens upon Him. LHU 273.4
To such we would say, Recount what God has done for you. Tell Satan that you do not trust in your own righteousness, but in the righteousness of Christ. Keep the mind filled with the precious promises found in the Bible, and when Satan comes in like a flood to overwhelm you, meet him with the weapon which the Word of God has provided, “It is written.” This will break his power and give you the victory (Historical Sketches of the Foreign Missions of the Seventh-day Adventists, 129, 130).
