You should read Bavinck's and Mueller's books and read the Lutheran and Calvinist confessions, if you want to know about the two classical Evangelical traditions. Most Protestants nowadays are crypto-Catholics/Orthodox in regards to soteriology; they are synergists, which Lutherans and Calvinists reject as unbiblical. The essential part of Sola Gratia is unconditional election.Right now my church is wherever I am. I stopped going to Church even though I know the Bible says I am supposed to. It seems to me like Amos 8:11 came true:
“Behold, the days are coming,” says the Lord GOD,
“That I will send a famine on the land,
Not a famine of bread,
Nor a thirst for water,
But of hearing the words of the LORD.
Amos 8:11 NKJV
I can't find a church where the Word is preached honestly, except preachers from at least 150 years ago on the Internet. So I do my best to be a Christian by myself in my day-to-day life without going to Church.
About election and predestination, I know that was a big issue among the Reformers. I know major leaders were divided, and churches split because of it.
I decided to follow Charles Spurgeon's advice and believe everything in the Bible is 100% true, even if it seems contradictory. Using that as a starting point, over time, things like election and predestination seem to make more sense to me. I know God knew everything beforehand because He knows everything, and has total control over everything in His creation. Of course I also have a free choice to move toward or away from Him, because that's my obvious moment-to-moment experience. Also, that is the only way true love and goodness can work, they have to be done by choice. I know I am not good by myself, also from personal experience, I know it's impossible for me to do the right thing by my own power. So I attribute anything good I think, say, or do to the power of Christ, God's promised Redeemer, working in me. I believe His suffering on the cross is how God gave me a new nature that wants to do good things. Still, much of the time I can't help thinking, saying and doing wrong because I only have the final victory over sin at the point of death when my mortal body which is full of sin finally dies. When my sin is very strong in life I follow Martin Luther's advice and "let my sin my strong, but my faith in Christ greater." Those times are when the atonement becomes very important, to keep away despair and keep my faith strong. Of course every time, things turn around and get better, and it is all due to God.
Thankfully none of us need to understand or agree on these things, because the Gospel is simple enough that even a simple, uneducated person can understand it and benefit from it. I think we have extremely limited knowledge while we're on Earth, and have forgotten many important, simple things that will make a lot more sense one day. I remember feeling a much stronger knowledge of who I was, where I came from and was going, and my relationship to God as a small child than I do today. I think more time on Earth just makes us forget more, but knowing Christ teaches us and fixes all those problems.
There are holy paradoxes in Scripture. Here is an article on the differences between Lutheran and Calvinist predestination, which mentions this point. https://www.firstthings.com/blogs/f...-predestination-isnt-calvinist-predestination
You also could read the Brief Statement of the Missouri Synod, it speaks on such paradoxes in the article On the Election of Grace. The articles on conversion and justification could also be of interest for you.
