信仰 means firm belief, faith, persuasion, conviction, and sometimes religion or creed in Chinese, Japanese Kanji, and old Korean Hanja.

This clearly fits the religious connotation of the English word “devotion.”

This is often used to refer to a person of faith or a religious person.

This can be directly translated as “firm belief,” “creed,” “conviction,” or simply as “religious,” depending on context.

Some will also use this to mean “trust in God” in Japanese (though the term for God is not actually in this title).

It should be noted that this word is a little strange alone on a wall scroll.

While this can be pronounced in Japanese, it’s not a great selection for a wall scroll if your audience is Japanese.

南無釋迦牟尼佛 is a Buddhist chant or prayer of respect to the Shakyamuni Buddha.

Some will translate this as the Buddhist vow.

The first two characters, 南無, are sometimes translated as “amen”; others will translate it as “belief in” or “homage to.”
To expand on this, 南無 can also mean “taking of refuge in” while representing devotion or conviction. 南無 as with most religious concepts or words, different people or denominations will have varying definitions.

信心 is a Chinese, Japanese, and Korean word that means confidence, faith, or belief in somebody or something.

The first character means faith, and the second can mean heart or soul. Therefore, you could say this means “faithful heart” or “faithful soul.”

In Korean especially, this word has a religious connotation.

In the old Japanese Buddhist context, this was a word for citta-prasāda (clear or pure heart-mind).
In modern Japan (when read by non-Buddhists), this word is usually understood as “faith,” “belief,” or “devotion.”
