People often talk about how faith is important; but blind faith is dangerous. In the Tenrikyo religion, our faith is based on the Ofudesaki. We believe that these verses come from God. God tells us that God will use reason to help us.
Kono yo wa rii de semetaru sekai nari
Nanika yorozu o uta no ri de seme 1-21
In this world, I will attack by reason. What appears in the world,
in everything all will be attacked with the reason in verse.
God does not want us to have blind faith. God tries to explain everything in the Ofudesaki by reasoning with us. What information is most important for us to understand? God wants us to understand the heart/soul/spirit. In the first verse is the following:
Yorozuyo no sekai ichiretsu miharasedo
Mune no wakarita mono wa nai kara 1-1
Looking all over the world and through all ages,
there is no one who understands the heart/soul/spirit.
Why is it so important that we understand the heart/soul? God even classifies people into two different classes. Those who understand the soul are called nihon, and those who do not are classified as kara.
Korekara wa kara to nihon no hanashi suru
Nani o yu tomo wakari arumai 2-31
From now on, I will talk about kara and nihon.
You may not understand what I say.
Sore shirazu nanto omote kami taru wa
Mune ga wakaran Tsukihi zannen 10-90
Unaware of this, what are you thinking? The high mountains (nihon)
cannot understand the heart. Oh, the regret of God.
Also in the first verse (1-1) , most people will define kara as because, but could it also refer to the people who do not understand the soul/heart?
Mune no wakarita mono wa nai kara
Understanding the soul/heart is the first requirement that God expects from us. Why is it so important for us to understand the heart/soul? Understanding the soul helps us understand why we have joy or suffering. We reap what we have sowed because of our own souls/hearts. This explains karma or innen, but more important by understanding the soul, we can purify our minds and live a joyous life.
God wants us first purify our own minds by understanding the soul/heart. Then God wants us to share the truth of the soul/heart to the people around us (nioigake and hinokishin). Finally we must have faith in God and Oyasama, which most Tenrikyo have, to perform the Joyous Service. This is faith based on reason. I believe that faith based on reason will bring people to our places of worship to be saved.
