Booth does not get you saved eternally, neither does any other preacher or person. God saves us with the new birth by exchanging our hearts (Eze 11:19-20) and putting his Holy Spirit within us, as explained in Eph 2. God saves us eternally by his sovereign grace, without help from any man. According to 1 Cor 2:14 the natural man, before he has been born again, does not understand the things of the Spirit, and it says that he, indeed, can not understand, therefore, he will not repent of breaking a spiritual law that he cannot understand, he, also, cannot believe in spiritual things, nor accept spiritual things, until he has been born again. Once he has been born again with the indwelling of the Holy Spirit, then he can repent of breaking a spiritual law, and confess Jesus as his Savior, and believe in Spiritual things. The natural man only has faith of man. The born again man has spiritual faith, because spiritual faith is a fruit of the indwelling Holy Spirit.Staying at home for these few weeks could save your life. You can get saved wherever you are. Christians are too tied to a building. Whether you agree with Booth or not, he met people where they were in the streets and got them saved. Noit every sinner is going to come to your church.
Believing and repenting doesn't deliver you eternally? Pray tell, what does?
This is why Jesus instructed his Apostles to go and preach to the lost sheep (God's born again children of the house of Israel) They were not lost eternally, but were lost to the knowledge of the gospel. It does no good at all to preach to the natural man, who cannot understand the things of the Spirit. After you have been born again, then, and only then, can you have the ability to understand to believe, repent, confess, accept Jesus as your Savior, pray, or do anything that is of a spiritual nature.
