Reminds me of this, which is usually said in my local church as an invitation to Holy Communion:

"Come to this table, not because you must but because you may, not because you are strong, but because you are weak.

Come, not because any goodness of your own gives you a right to come, but because you need mercy and help.

Come, because you love the Lord a little and would like to love him more.

Come, because he loved you and gave himself for you.

Come and meet the risen Christ, for we are his Body"
