Thirst is a condition, not something someone 'causes.' All of us thirst -- for love, for peace, for joy, for companionship. This is universal. It is what we do about this thirst that makes all the difference. We have a choice: to drink from the poison waters of the lie or the life-giving waters of the truth. The choice is real. Both are available to each of us.
God does not change a person's heart against that person's will. This is why the writer to the Hebrews BEGGED them not to harden their hearts as their ancestors did in the wilderness when they rebelled against God. This is why, in Isaiah 1:18, God Himself invites "Come, let us reason together..." Both of these are addressed to the unregenerate, as one can see from the context. Christ invites ALL to labor and are heavy-laden to come to Him for rest. What is that labor? To follow all sorts of directions and laws to find what they thirst for!
All religions of the world are founded on the fact that man is not right -- something needs fixing, or exalting, or redeeming, or changing -- whatever term is used. And all except one tell the person it must be done by himself and his own actions or meditations or gifts or whatever. The onus is on him. Only one -- Christianity -- offers the invitation from God to 'come'. He has taken care of everything. He will change you. You will be given a new heart, a new life, and the promise of eternity with Him.
The invitation is to all and the Bible says plainly He is not willing that one should perish. But He has given us our own wills so that, in following Christ, we might be able to say "Nevertheless, not my will but Thine be done." So while He is not willing that any should perish, and has, at His own expense, made the way for all to be reconciled to Him in fellowship and faith, He has allowed us our own wills to respond as we choose to Him.
This is the only possible way a being capable of loving could be created. For love is a decision, not an emotion, and a decision is worth nothing if it is programmed or forced into something. It is worth something only if there is equal opportunity to choose the other way.
We were created to love and be loved. That can only happen in and through Christ because of our sin natures. But He tore the curtain and opened the way for each and every one of us.
Which way we then walk, however, is up to us. To Him or away from Him. Accept or reject the gift. If the person is chosen before time to accept or reject, then the choice is not real but fake -- a lie in and of itself. There is no choice. Yet the Bible tells us to choose whom we will serve and Jesus mourns Jerusalem for they were not willing to come to Him. His will was for them, but theirs was against Him. And He allowed them their will, although, being God, He certainly did not have to.
It is the same with all of us. Most men, I think, cause God to mourn.
