shine like the sun

If this simile is not understandable in your language, you can use: "be as easy to see as the sun." (See: rc://en/ta/man/jit/figs-simile)

Father

This is an important title for God. (See: rc://en/ta/man/jit/guidelines-sonofgodprinciples)

He who has ears, let him hear

Jesus is emphasizing that what he has just said is important and may take some effort to understand and put into practice. The phrase "has ears" here is a metonym for the willingness to understand and obey. See how you translated a similar phrase in Matthew 11:15. Alternate translation: "Let the one who is willing to listen, listen" or "The one who is willing to understand, let him understand and obey" (See: rc://en/ta/man/jit/figs-metonymy)

He who has ... let him hear

Since Jesus is speaking directly to his audience, you may prefer to use the second person here. See how you translated this in Matthew 11:15. Alternate translation: "If you have ... listen" (See: rc://en/ta/man/jit/figs-123person)
