If There is one thing lyrics by Tim Hughes from the album " Here I am to Worship "

You call first to love Your name, to worship You
To please Your heart, Our one desire Oh Lord

If there’s one thing we are called to do
Is to love You, to adore You
We will bring our all and worship You
Bow before You, as we love You

Your honor Lord, Your name is renowned
We long to see
So let the glory of Your name be praised

I will celebrate this love
Jesus You are everything to me
Furthermore what can I do?
I will give this heart , this life to You
