Genesis 1:6-8

 'And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters. And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so. And God called the firmament Heaven. And the evening and the morning were the second day. ' Genesis 1:6-8 https://my.bible.com/bible/1/GEN.1.6-8
God creates by His Word. God's Word is also what creates in us a clean heart.All we have to do in order to get this clean heart is to call upon the Lord.

For whosoever shall call upon the name of the Lord shall be saved.

Something that gets in our way is us.  God's Word says that are hearts are wicked. 

Please don't let your heart get in the way of coming to a saving knowledge of Jesus.

The heart is deceitful above all things, and desperately wicked: who can know it?

Humbly seek after God.  He won't hide from you if you are honest.  

If you need someone to talk to about Jesus, I would be honored.
