Expect great things from God; Attempt great things for God. -William Carey, missionary to India
To attempt great things for God you have to stand your ground. You can't expect God to do great things through you if you aren't willing to go out and attempt something for Him.
There's going to be doubters. There's going to be trouble makers. There's those who are going to hold on to the past and don't want to change. But God wants us to move forward. God will increase what we give to Him, but we have to give it first. We can't let the "nay sayers" sway us.
What do you think a soul is worth to Christ? Christ thought it was worth His life! He doesn't want us to spare when there's a field white unto harvest. It's worth doing and it's worth doing right! You might not see the results, but God does. Do you think it's worth the cost? God does!
