『Theology of Love』 emphasizes that the will to marry should be a mission.
What sustains marriage is not the couple's love, but the covenant, and enduring love must be provided in Christ.
The apostles' statement is the sum total of love and the supremacy of love that humans can recognize. If we love, we must follow their teachings, be patient, not act rudely, and believe in and hope for the kingdom of God.
Rather than asking theological questions, the author defines love as a decision, not an emotion, in a world where everyone acts according to their own will. Through the author's married life, the author allows readers to experience true love, dating, marriage and family, childbirth and childrearing.

The main focus of this book is on biblical theological perspective.
It was named ‘Love Theology’ with the intention of highlighting its uniqueness.

--- p.27

What does the expression "love theology" mean? The word "theologia" means "God speaks" or "(we) speak of God."
Therefore, the theology of love means 'God speaks through love' or '(we) speak of God through love.'

--- p.30

If Christ and the Church are the ultimate 'reality,' then the marital relationship between husband and wife is a temporary 'shadow.'
To borrow John Piper's expression, the former is the 'original' and the latter is the 'copy'.

--- p.40

The apostle's statement is the sum total of all love in the world and the supremacy of love that can be recognized by human beings.
It is life itself that makes the dead heart of a sinner beat.

While doing couples counseling, I discovered something interesting.
The period when young people start dating and their relationships go wrong or break up is concentrated between about 6 months and 1 year.
…is almost identical to the hormonal state that begins when you fall in love.
--- p.61

That's according to experts who studied twelve couples in love.
It is emphasized that the absence of hormone secretion does not mean that love disappears.

--- p.73

The standard for establishing a loving will toward marriage is each other's mission.
Christian young people need to understand that love alone is not the only reason for marriage.

--- p.91

But because of our fallen nature, it takes some training to recognize it that way.
When we are in a state of intense sexual arousal toward the opposite sex, we almost unconsciously think of love for God and love for a partner as conflicting concepts.

--- p.109

When two people experience a state of intense spiritual awakening together, they gain control over their desires for each other.
Also, as they naturally enjoy sexual attraction towards each other, a strong rationality is created that allows them to love each other.

--- p.121

The 'nakedness of our whole being' is also an expression that characterizes our relationship with God.
Because you know my most intimate parts and want to align all my desires with your glory.
Our faith is a willingness to acknowledge that our very existence is naked before God.
--- p.128

If you love, you must be patient, as the apostles taught.
While passionately loving God, we must not be rude to Him.

--- p.147

I am convinced that when lovers' fundamental desires are thoroughly subordinated to God's sovereignty and will, a fundamental conversion of their view of love will occur.

--- p.154

We must truly put into practice His words: “Love one another as I have loved you” (John 13:34).
I hope you can let go of the idea that love matters are an exception to that saying!
--- p.172

The love between lovers is a communal attribute, and at the same time, it is directly connected to the community in which they live.
Because of the nature of love, their love cannot remain in it forever.

--- p.178

The love I enjoyed with my wife before marriage was not a covenant love.
Because ‘that love’ begins from the moment of marriage when God joins us together as one body.
You don't get married because you love, you get married to love.
