Ben Seewald is settling into married life but he's still finding the time to share about his faith in God with his 34,000 Facebook fans.

Mr Jessa Duggar, of 19 Kids and Counting fame, shared a heartfelt message over the Thanksgiving holiday in which he talks candidly about how he should have been found guilty for his sins, but was cleared because of God's grace.

He goes on to write that he understood grace when he understood how much he had received.

"I never saw the true depth of how much I have to be thankful for, until I realised how much I'd been given and caught a glimpse of how undeserving I was," he said.

"That's when I understood grace. God's grace is not something that can be earned by us. But grace was earned by God. It cost Him something...It cost something because God is Holy and Just, and cannot merely overlook sin. Yet He is gracious and desires to forgive sinners."

Ben probably feels like he's got a lot to be thankful this season, after marrying his sweetheart Jessa a few weeks ago.

The wedding was the second for the Duggar family this year, after Jessa's sister Jill married Derick Dillard in the summer.

Ben goes on to invite his fans to believe in God's grace and receive the forgiveness that is being offered to them too.

"I'm so grateful He didn't leave me to myself, to die bearing my own guilt. I'm grateful for His intervention in my life! I'm SO thankful for God's grace! You can have God's grace today," he shared.

"You can have forgiveness and freedom from sin, freedom from guilt in your past and future! Jesus says "Whoever comes to me I will never cast out." (John 6:37b) Trust His promise today!"

Last week, Ben revealed that he just loves "love", and especially love in action, love that "seeks nothing in return" and is shown in spite of "trying situations". He then invited fans to share their own experiences of unconditional love and many answered back that they had experienced it in Jesus, their spouses, and being parents.

In one touching comment, a Facebook fan wrote: "When my dad was in the end stages of alzheimers and couldnt recognise any of us, my mom still would hold his hand and say " I love you Walt" and my dad would squeeze her hand. He knew my mom! Now thats unending unconditional love. They were married 44 yrs when he passed. [SIC]"
