There is to be in the churches a wonderful manifestation of the power of God, but it will not move upon those who have not humbled themselves before the Lord, and opened the door of their heart by confession and repentance. (Maranatha – 219)

Let there be a work of reformation and repentance. Let all seek for the outpouring of the Holy Spirit. As with the disciples after the ascension of Christ, it may require several days of earnestly seeking God and putting away of sin. 

When God's people are worked by the Holy Spirit, they will manifest a zeal that is according to knowledge. . . . They will reflect the light that God has been giving for years. The spirit of criticism will be put away. Filled with the spirit of humility, they will be of one mind, united with one another and with Christ. (My Life Today – 58)

There is great need today of just such sincere, heartfelt repentance and confession. Those who have not humbled their souls before God in acknowledging their guilt have not yet fulfilled the first condition of acceptance. If we have not experienced that repentance which is not to be repented of, and have not confessed our sin with true humiliation of soul and brokenness of spirit, abhorring our iniquity, we have never sought truly for the forgiveness of sin; and if we have never sought we have never found the peace of God. The only reason why we may not have remission of sins that are past is that we are not willing to humble our proud hearts and comply with the conditions of the word of truth. There is explicit instruction given concerning this matter. Confession of sin, whether public or private, should be heartfelt and freely expressed. It is not to be urged from the sinner. It is not to be made in a flippant and careless way or forced from those who have no realizing sense of the abhorrent character of sin. The confession that is mingled with tears and sorrow, that is the outpouring of the inmost soul, finds its way to the God of infinite pity. Says the psalmist: "The Lord is nigh unto them that are of a broken heart; and saveth such as be of a contrite spirit." (5 Testimonies – 636)

1 John 1:9 – If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. 

2 Corinthians 7:9-10 – Now I rejoice, not that ye were made sorry, but that ye sorrowed to repentance: for ye were made sorry after a godly manner, that ye might receive damage by us in nothing. For godly sorrow worketh repentance to salvation not to be repented of: but the sorrow of the world worketh death.
