New parents Derick and Jill Dillard from 19 Kids and Counting are determined to be the best mum and dad they can be to their firstborn son Israel David, and they have committed to raise him to become a man who loves God and all the people around him.

Both Derick and Jill feel so blessed that they were able to get pregnant so early into their marriage, and Jill said it's something that they will never take for granted.

"It's so neat just to be a mom and it's something that I've dreamed about - being parents together. It's amazing what a privilege it is to have this blessing, this little boy," said Jill. "We're so grateful to God and we pray that we can raise him to be a man who loves God with all of his heart and love others with a servant's spirit."

When Israel David came into the world, Derick said he finally understood the depth of love between a parent and a child.

"One thing my mom told me that stuck with me right after Israel was born was, 'Now you can begin to imagine how much I love you.' And it really is indescribable," he said.

Derick added that he still cannot fully understand the love there is between a parent and a child because it is so profound. Whenever he looks at his new baby, all Derick can think is how much he loves him.

"It just hurts my heart how much I love him. I just want the best for him and protect him, teach him, and raise him to be a Godly man," he said.

The young couple say that being first-time parents is "awesome" and it's an exciting experience for them to learn the intricacies of parenthood.
