The Reformation, triggered by Martin Luther (1517), went beyond simple church reform and became an opportunity to restore the Bible's teachings on 'grace', especially 'salvation'.
Later theologians summarized the various theological trends of that time into the 'Five Sola', and among the various confessional documents written at that time, the Canons of Dort (1619) clearly expressed this in the five articles called 'TULIP'.

"Garden of Grace: Reformed Faith Encountered through the Bible and Confessions of Faith" explains the meaning of each of the five SOLA and TULIP articles by connecting them to the Bible text, helping readers apply them to their religious life.
Additionally, the full text of the Canons of Dort and some of the catechisms translated by 'People of the Book' have been included to enhance readers' understanding.
This book will be helpful to those who are curious about how the Reformation relates to our religious life today.

Our predecessors in the faith have well summarized the Bible's teachings on the grace of salvation.
These are the doctrines called Total Depravity, Unconditional Election, Limited Atonement, Irresistible Grace, and Perseverance of Saints.
Many people call these five doctrines "TULIP," an acronym for "Tulip." TULIP is neither a complex or difficult doctrine nor a slogan exclusive to Calvinists.
This is the way of salvation and another name for grace that the Bible speaks of, and it is the reason for the thanksgiving and praise we must offer to God.

Therefore, we must bow down before this amazing grace of ‘unconditional election’ and offer thanks and praise to God.
Just because it is ‘unconditional’ does not mean that you will be saved no matter how you live.
It means that God saved us even though we were unable to meet the conditions.
Unconditional election praises the greatness of God's salvation despite our incompetence, depravity, and misery.

The Lord spoke not of vague possibilities, but of facts He had already established.
You have already solved and prepared the salvation for him.
'Zacchaeus' means 'pure person'.
But he was not pure, and he could not purify himself.
The Lord purified him.

Explanations require patience.
Anyone who has tried it knows.
It would be nice if you could understand and understand everything with just one explanation, but that rarely happens.
I have to explain and explain again until you understand.
Let alone understanding, the other person doesn't even listen attentively.
Even if it gets a little longer, I lose focus.
My body twists, my mind wanders, and my eyes close slowly.
It is difficult to explain if you do not respect and treat the other person as a person, that is, if you do not 'love' them.
Jesus explained the Scriptures to them about himself.
He explained it calmly, one by one.

We often misunderstand the term ‘religious life’.
Because they misunderstand faith.
We often confuse faith in Jesus with 'expectation' - the hope that something will happen.
So, I mistake a life where everything I want and desire comes true as a ‘life of faith.’
However, ‘religious life’ is living, literally living reality.
Sometimes that reality can be so hard and painful.
You may be shunned or hated by people.
You may suffer losses.
You may become poor, your body may become sick, your mind may become sick, and you may feel sad, anxious, and panicky.
That's all reality.
A life of faith is not about all these realities disappearing, but rather about living through the reality before us with faith in Jesus.

The Medieval Church period, which lasted approximately 1,000 years from the 5th century to the 16th century, was the period in the history of the Church when its authority and prestige were at their strongest.
But that authority and prestige actually corrupted the church.
The decisions of the Pope or the Council, and the long-standing traditions of the Church, have become equal in authority to, or sometimes even surpass, the Bible.
In response to this, the elders of the faith, especially the reformers, began to proclaim again the important contents of faith that were clearly revealed in the Bible.
It is more accurate to view them as rediscovering the precious legacy of faith that had been buried beneath the corruption of the church.
These important contents that emerged through the theology of the religious reformers were organized into five themes by later theologians, and these are called the 'five solas'.

The reason our faith in Christ alone is wavering is not because church buildings are collapsing or the number of church members is decreasing.
Because the issue of 'sin' is not addressed and is taken lightly.
These are such times.
Many churches today do not speak of 'sin'.
Instead of the word sin, we purify it with words like 'mistake', 'disease', and 'fall'.
God's wrath, which judges sin, and hell, the eternal judgment that those whose sins are not forgiven, will receive, are also not mentioned.
I try not to cause discomfort to people.
But the Bible clearly points out our sin.
It tells us how terrible our sin is, and that God hates sin, is angry, and judges it.
When God speaks, we must speak too.

--- pp.120-121

Therefore, true grace is not a momentary emotion.
It is not a fleeting emotion like excitement or joy that may evaporate at any time.
Grace makes me aware of my misery and sinfulness, and makes me realize the glory of God, His power, and His love.
Afterwards, by developing the right faith, we live a new life worthy of God's grace, that is, a life as children of God.
It is not a whirlwind of emotions that comes and goes.
These are long, even eternal, moments when our very being (our whole being) is fundamentally transformed.
The cause and beginning of this ultimate change, the basis of all circumstances, is grace.

--- p.140

Have you ever asked the Lord this question? We should always ask this question.
In an age when the value of salvation has been lost, we must be more serious about the issue of our salvation.
If you take the grace of salvation lightly, that is not Christianity.
I must always reflect on my faith and constantly ask the Lord.
When that happens, Jesus will give us the answer, just as he gave it to Nicodemus.
