Many times when the Lord has opened the way for brethren to handle their means to advance His cause, the agents of Satan have presented some enterprise by which they were positive the brethren could double their means. They take the bait; their money is invested, and the cause, and frequently themselves, never receive a dollar. CS 235.1
Brethren, remember the cause, and when you have means at your command lay up for yourselves a good foundation against the time to come, that you may lay hold on eternal life. Jesus for your sakes became poor, that you through His poverty might be made rich in heavenly treasure. What will you give for Jesus, who has given all for you?—Testimonies for the Church 5:154, 155.
