“Oh! I love God’s ‘shalls’ and ‘wills.’ There is nothing comparable to them. Let a man say ‘shall,’ what is it good for? ‘I will,’ says man, and he never performs; ‘I shall,’ says he, and he breaks his promise. But it is never so with God’s ‘shalls.’
If He says ‘shall,’ it shall be; when He says ‘will,’ it will be. Now He has said here, ‘any shall come.’ The devil says ‘they shall not come;’ but ‘they shall come.’ Their sins say ‘you can’t come;’ God says ‘you shall come.’ You, yourselves, say, ‘you won’t come;’ God says ‘you shall come.’
Yes! There are some here who are laughing at salvation, who can scoff at Christ and mock at the gospel; but I tell you some of you shall come yet. ‘What!’ you say, ‘can God make me become a Christian?’
I tell you yes, for herein rests the power of the gospel. It does not ask you consent; but it gets it. It does not say, ‘Will you have it?’
But it makes you willing in the day of God’s power. Not against your will, but it makes you willing. It shows you its value, and then you fall in love with it.”
