An undivided heart.

There is none like you among the gods, O Lord,
nor are there any works like Yours.
All the nations you have made shall come
and worship before You, O Lord,
and shall glorify Your name.
For You are great and do wondrous things;
You alone are God.
Teach me Your way, O LORD,
that I may walk in Your truth;
unite my heart to fear Your name.

I give thanks to You, O Lord my God, with my whole heart,
and I will glorify Your name forever.
For great is Your steadfast love toward me;
You have delivered my soul from the depths of Sheol.
—Psalm 86:8-13, ESV
