This one is difficult because "Lord" so often means Christ, but here, praying to our Father is one of the ways to seek the "Lord" so here, I'm taking "Lord" to mean "Heavenly Father." I changed "The Lord" to "my Parents," but because of the syllables, you have to sing "my" as a pick up note.
I’ll seek my Parents early while in my youth,
And they will help me to know the truth.
I’ll search the scriptures and find them there,
Then go to our Parents in fervent prayer.
I’ll seek my Parents early, and I’ll obey
Their living prophets in all they say.
I’ll keep their commandments; their love will abound.
I will seek my Parents early, and they will be found.
