words to hold on to

It's been a tough week or so. . . I've definitely been holding on to these words for dear life.

Romans 8:26-27 (NIV)
In the same way, the Spirit helps us in our weakness. We do not know what we ought to pray for, but the Spirit himself intercedes for us with groans that words cannot express. And he who searches our hearts knows the mind of the Spirit, because the Spirit intercedes for the saints in accordance with God's will.

Psalm 30:11-12 (NASB)
You have turned for me my mourning into dancing;
You have loosed my sackcloth and girded me with gladness,
That my soul may sing praise to You and not be silent
O LORD my God, I will give thanks to You forever.
