He desires to save all.
For God so loved the world that he gave his only begotten Son, that whosoever believes in him should not perish, but have everlasting life. John 3: 16. But God commends his love towards us, in that while we were yet sinners, Christ died for us Rom 5: 8. But God, who is rich in mercy, for his great love wherewith he loved us, even when we were dead in sins, has quickened us together with Christ, (by grace you are saved.) Eph. 2: 4,5. The Lord is good to all and his tender mercies are over all his works. Ps. 145: 9.
It matters not which view we take. No theory of the loss of a single soul can be adopted that does not drag to ruin one or more or the attributes of God. Does he not desire the welfare of that soul? Then he is deficient in goodness. Can he not plan its welfare? Then he is not infinitely wise. Can he not execute the plan he desires? His power is limited. To be infinite in all his attributes he must be so good as to desire, so wise as to plan, and so powerful as to execute the good of all. The God of Calvinism is strong but bad; the God of Arminianism is good but weak. The Christian God has the faults of neither and the merits of both.
If, therefore, we say that God will not and cannot, or can but will not, or will but cannot, save every human soul, we limit him in some direction, but if he will and can, then the result contemplated by the Universalist faith must be accomplished.
