Four things that cloud people’s minds and keep them bound in a mindset even when the Lord has asked us to lay this down:

-Tradition: I’ve done this all my life.  
-Sentiments/passion: This means something to me so I don’t want to let it go. 
-Loyalty. This person is loyal to me. I can’t afford to do away with them even when God asks us to. We counter  God's voice and justify why they have to stay. We want them to stay because we are dependent on them in some way.

Let us quickly review some verses of Psalm 147 as seen below-

Psalm 147

1 Praise the Lord.
   How good it is to sing praises to our God,
   How pleasant and fitting to praise Him!

4 He determines the number of the stars
   and calls them each by name.

5 Great is our Lord and mighty in power;
   His understanding has no limit.

6 The Lord sustains the humble
    but casts the wicked to the ground.

7 Sing to the Lord with grateful praise;
   make music to our God on the harp.
