In chapter six of The Way of Life, Charles Hodge summarized some different ways the Bible speaks about justifying faith. One of those examples is faith as submission (cf. Rom 10:3).
Another term by which faith is expressed is submitting. This is not to be understood as meaning a submission to the will of God as a sovereign ruler, a giving up all our controversy with him and resigning ourselves into his hands. All this is duty, but it is not saving faith. The submission required is submission to the revealed plan of salvation; it is the giving up all excuses for our sins, all dependence upon our own righteousness, and submitting to the righteousness which God has provided for our justification. This is what the Jews refused to do, and perished in unbelief. This is what we must do, in order to be saved.
Men, when sensible of their guilt and danger, are perplexed and anxious about many things. But there is only one thing for them to do. They must submit to be saved as ungodly, as sinners, as entirely undeserving, solely for Christ’s sake. They must consent to allow the robe of his righteousness to be cast over all their nakedness and blood, that they may be found in him, not having their own righteousness, but the righteousness which is by faith in Jesus Christ. Then will they be prepared to join that great multitude which stand before the throne and before the Lamb, clothed in white robes and palms in their hands, crying with a loud voice, ‘Salvation to our God who sitteth upon the throne, and to the Lamb, for thou wast slain, and hast redeemed us unto God by thy blood, out of every kindred, and people, and tongue, and nation, and hast made us unto our God kings and priests.’
It is thus that the Bible answers the question, What must we do to be saved? We are told to believe on the Lord Jesus Christ; and to set forth the nature, the object and office of this faith, the Scriptures employ the most significant terms and illustrations, in order that we may learn to renounce ourselves and our works, and to be found in Christ depending solely upon what He has done and suffered as the ground of our acceptance with God. Those who thus believe, have passed from death unto life; they are no longer under condemnation; they have peace with God and rejoice in hope of his glory. As this faith unites them with Christ, it makes them not only partakers of his death, but of his life. The Holy Spirit, given without measure to him, is through him given unto them, and works in them the fruits of holiness, which are unto the praise and glory of God.
