However, you could express a similar sentiment with phrases like:
* "I ke akua" (pronounced "ee keh ah-koo-ah") which means "in the hands of the gods" or "in the hands of the divine".
* "I ka mana" (pronounced "ee kah mah-nah") which means "in the power" or "in the strength" and could be interpreted as trusting in a higher power or spiritual force.
* "Ma ka mana o ke Akua" (pronounced "mah kah mah-nah oh keh ah-koo-ah") which means "in the power of the divine".
Ultimately, the best way to express "in God's hands" in Hawaiian would depend on the specific context and the individual's own spiritual beliefs.
