Hymn Lyrics Search - Name That Hymn

I am looking for the complete lyrics of a song sang by John and Linnie Olson on a radio program. I believe they were missionaires with Central American Mission.
I am not sure of the name of the song: Do you care?
The words are something like this:
Do you know that Jesus loves you, do you care,
Children lost and voices crying, do you care.
Can you say with God's dear Son, not my will, but Thine be done.
Can you hear them, does it matter, do you care.

Do you know that Jesus loves you, do you care?
Do you know He died to save you, do you care?
Son of God and man is He, yet he died upon that tree,
Do you love Him, does it matter, do you care?

It is morning, the sun's in my heart
Even when it's cloudy and gray.
It is morning, the Son's in my heart
'Gonna be a wonderful day.
