"One of The [Salvation] Army's central doctrines and most valued and precious experiences is that of Heart Holiness. The bridge which The Army throws across the impassable gulf that separates the sinner from the Saviour -- who pardons that He may purify, who saves that He may sanctify rests upon these two abutments -- the forgiveness of sins through simple, penitent, obedient faith in a crucified Redeemer, and the purifying of the heart and empowering of the soul through the anointing of the Holy Spirit, given by its risen and ascended Lord, and received not by works, but by faith.
Remove either of these abutments and the bridge falls; preserve them in strength, and a world of lost and despairing sinners can be confidently invited and urged to come and be gloriously saved.
The first abutment is deep grounded on such assurances as these: 'There is forgiveness with Thee, that Thou mayest be feared' and 'If we confess our sins, He is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.'
And the second firmly rests on such Scriptures as these: 'And God, who knoweth the hearts, bare them witness, giving them the Holy Ghost, even as He did unto us; and put no difference between us and them, purifying their hearts by faith.' 'If we walk in the light as He is in the light, we have fellowship one with another, and the Blood of Jesus Christ His Son cleanseth us from all sin;' and 'Ye shall receive power after hat the Holy Ghost is come upon you.'"
