There is a lot of enthusiasm these days about the sovereignty of God.  This doctrine is a foundational truth.  Our lives as Christians depend on this great truth.  Knowing that God is in control of His universe calms us in the midst of life's storms.   Our salvation was initiated by God and Christ is sovereign in salvation.   A truth that may appear to be in opposition to this truth is the responsibility of man.  Man has a huge responsibility to believe.  Charles Spurgeon said, "I see in one place, God presiding over all in providence; and yet I see, and I cannot help seeing, that man acts as he pleases, and that God has left his actions to his own will, in a great measure.  Now, if I were to declare that man was so free to act, that there was no presidence of God over his actions, I should be driven very near to Atheism; and if, on the other hand, I declare that God so overrules all things, as that man is not free enough to be responsible, I am driven at once into fatalism.  That God predestines, and that man is responsible, are two things that few can see." How can these be reconciled?  The answer:  they do not need to be reconciled.  There is no need to reconcile friends.  If they seem contradictory - the apparent contradiction is our inability to fathom the mystery of salvation.  So when I speak about the enthusiasm concerning the sovereignty of God - I want to be sure we're not forgetting the responsibility of man.  So let's embrace with great joy and relief that God is sovereign.  And let's not diminish human responsibility. 

Here's the best sermon on this subject I've come across
