'tis So Sweet To Trust In Jesus Lyrics

'Tis so sweet to trust in Jesus,
And to take him at his word;
Just to rest upon his promise,
And to know, "Thus saith the Lord."

Refrain:
Jesus, Jesus, how I trust him!
How I've proved him o'er and o'er!
Jesus, Jesus, precious Jesus!
O for grace to trust him more!

I'm so glad I learned to trust thee,
Precious Jesus, Savior, friend;
And I know that thou art with me,
Wilt be with me to the end.
(Refrain)
