Terach left with Sarai, Avram, and Lot to go to Ca'anan, mostly because it was his dead son's inherited land. So they left but stopped along the way.
Then HaShem speaks to Avram, tells him to Lech Lecha -- go forth, to yourself. Avram leaves with Sarai and Lot and heads to Ca'anan, fulfilling the original destination goal. It's there that HaShem promises so much to Avram and his future offspring.
So essentially, the first bit of the journey was not enough and HaShem and to tell Avram to keep going. Would he have gone on his own? Would he have stayed with his father?
The truth is, I feel like this about my journey and my conversion.
I found and began my Jewish journey in the Reform movement of Judaism around 2002/2003 and after much teeth grinding and examination of myself, who I was, and where I was going, wound my way through other branches of Judaism until I landed at the doorsteps of Orthodoxy in 2008.
That first leg of the journey was like leaving my land with Terach and heading toward the land of my inheritance -- Judaism.
The second leg was HaShem telling me to go further, to go forth to who I was truly meant to be. To embrace that person I was.
I feel a bit like Avram. But only a bit.
