The choices you make as a Believer have a huge impact on your life and the lives of others. For it to be a godly impact, you must maintain a soft and tender heart towards God.
Choosing that kind of heart is up to you. He'll help you, but you determine the tenderness of your heart.
Psalm 95:7-8 (NIV)
Today, if only you would hear his voice, “Do not harden your hearts..."
He wouldn't have said that if you didn't have a choice in the matter. As Tarzan might have said it,
"Hard heart bad. Soft heart good."
