Hi Everyone, i need help to translate some of the lyrics of one song it appears in the game Genei Ibun Roku (SMT X FE)

Here is the romaji version of the lyrics, if someone can translate this to English it would be great

Romaji:
Ah, kimi wo yobu senritsu wa kono sora no hate he
Eien wo chikai, shukufuku wo sazukeyou

Mawaritsuzukeru sadame to shite mo
Ima wo ikite hoshii

Saa, mezame yo

Hikari wo ukete

Mamoritai mono ga aru
Toki wo koete mo kawarazu ni

Mamoritai hito ga iru
Ikiru riyuu ga soko ni aru

Saa, mezame yo
