Against Free Will

I thought that free will was generally accepted in all Christianity.
Ten years ago, I left the Methodist church (in fact, it was a branch from Methodist, not the main Methodist church) to another one because the pastor was profaning the sacred. He was basing his sermons on the importance of tithe reading Malachiah 3. I decided to scan all the Bible searching for tithe. It revealed to me that tithe was not possible to gentiles because we have no levites, no treasure house and even worse, tithe was related to food and sharing it, not money even though money existed at that time. In resume, this Methodist pastor, in particular, (please, do not generalize, the Lord works in Methodist churches too!) was at least ignorant, at worse, he was playing to say things in name of the Lord falsely. He was always joking in the pulpit saying things like: "open your eyes, Japanese" towards me. Amazing his lack of respect to the Word and to the congregation. Anyway,  I left this church.
In a new church, I tried to argument that no one could claim eternal life assurance due to free will to a friend. He asked:
- How do you know Free Will exists?
And after that, he gave me a book from A. Pink: "The Sovereignty of God". There is a chapter against Free Will.
I began to reason that it would be possible to have eternal life assurance in a deterministic view. I was somehow designed to belong to the Lord even before the Big Bang, the creation of the universe as in Ephesians 1. If it were true, it would be even truer that the Lord would lead me to repentance, to believe in Him and also, He would make me persevere in the faith. I had already repented and was a believer in Jesus, but I was missing some peace in my heart: I believed in a god that could not sustain me due to some kind of defect in me: the free will that would always made me sin.  I had been fighting against pornography for a long time. I could be free of it for months, but somehow, I was always attracted to it. I had to fight hardly not to type words that would lead me to porn in google. My flesh wanted porn, my spirit not. I thought that I was saved, but I had this fight as in Romans 7. Whenever I felled, I confessed my sins and I believed in His forgiveness. I failed so many times that I decided not to promise anything to the Lord as "I will sin no more".
The Lord was merciful to me and changed my desires. The Spirit gave me a new life with new desires. I really do not know exactly when, but I am quite certain it was after I realized how the Lord loves me so that He created me to Him, despite my problems and sins.
Today, I can not say that I have no desire at all to porn, but it is so small compared to before! I have been free from porn for some years, thanks to Jesus, my Savor, my Redeemer, my Lord. I have been believing that I belong to Jesus and it is as certain as one and one are two; and Jesus belongs to me. I eat Jesus, my Bread from Heaven; I drink Jesus, the Living Water. Jesus is mine and gives me life. I live because He lives.
Am I implying that Free Will is against the Bible as A. Pink did? Am I implying that I was not saved till I departed from the Free Will belief?
No, I am not. Perhaps, I was saved before; In fact, I think I was saved but I had a heavy life, I had to carry a heavy burden to follow Jesus and even worse, I was always displeasing Him because I knew deep in my heart that I was not living as He expected me to live. Now I think different: in Jesus, I know that I please Him. Today I really do not need to please anyone but the Lord. My mission is to glorify Him, to praise Him, to surrender to Him everyday. I have to write more words about Free Will. Today, I think that somehow the Bible is Arminian: they are not completed wrong; somehow the Bible is Calvinist: they are not also completed wrong or completed right. In fact, some verses say that man must choose, seek the Lord, depart from evil, etc.; and some verses say that it is the Lord who operates. Both are true. I have to write about it in another post.
