Plan of Salvation Class

Right now I'm in Plan of Salvation class, and I would just like to share some interesting quotes:

"Halfhearted Christians are worse than infidels; for their deceptive words and noncommittal position lead many astray. The infidel shows his colors. The lukewarm Christian deceives both parties. He is neither a good worldling nor a good Christian. Satan uses him to do a work that no one else can do." (Original source: 7BC 963)

"The youth especially stumble over this phrase, 'A new heart.' They do not know what it means. They look for a special change to take place in their feelings. This they term conversion. Over this error thousands have stumbled to ruin, not understanding the expression, 'Ye must be born again...' When Jesus speaks of the new heart, He means the mind, the life, the whole being. To have a change of heart is to withdraw the affections from the world, and fasten them upon Christ. To have a new heart is to have a new mind, new purposes, new motives. What is the sign of a new heart?--a changed life. There is a daily, hourly dying to selfishness and pride." (Original source: SD 100)
