1The Lord had said to Abram, “Go from your country, your people and your father’s household to the land I will show you.

2“I will make you into a great nation,

and I will bless you;

I will make your name great,

and you will be a blessing.^a

3I will bless those who bless you,

and whoever curses you I will curse;

and all peoples on earth

will be blessed through you.”^b

4So Abram went, as the Lord had told him; and Lot went with him. Abram was seventy-five years old when he set out from Harran. 5He took his wife Sarai, his nephew Lot, all the possessions they had accumulated and the people they had acquired in Harran, and they set out for the land of Canaan, and they arrived there.

Three points:
1: Pruning
2: Prophecy
3: Blessings

Pruning
The Lord told Abram to "leave" his people and his country and set out to the land He will show him.  In order to trust God, we are often told to leave something behind or God may remove it.  This is referred to pruning in the Bible.
John 15:2   - Every branch in me that does not bear fruit he takes away, and every branch that does bear fruit he prunes, that it may bear more fruit.

It wasn't until I started gardening that I understood pruning.  A neighbor used to take care of my gerbre daisies.  I thought I could just plant them and then they would grow without any work.  The daisies needed pruning.  The way she described it to me has ingrained forever in my mind in regards to God pruning us as His children and church.  As a part of it dies or makes it's cycle of life with the flower, then it needs to be pruned.  Pruning means to cut away from the flower, plant, or tree.  The roots push nutrients and water up to each part of the plant. The plant works extra hard to push nutrients and water (life) up to the dying parts. The living parts suffer, because the plant is using most of it's sources on the dying part, trying to revive it.  Therefore, the plant ceases to produce fruit or flowers.  If the parts that are dying are cut away from the plant, then the nutrients and water are able to free flow full force to the living parts, producing much fruit or flowers.  In order to grow, we must obey God and leave behind whatever He asks from us.

Prophecy
God tells Abram that He will make his name great and make him into a great nation.  Later in Scripture, we find that this means that Abram will have as many descendants as the stars.  If God tells you an outcome that has yet to come about, then this is a prophetic word.  Again, the only way to get to the outcome is through trusting God and obeying His Word.  Yes, we get off track and God helps us back into His will.  He is full of grace and love!  We will see later in Scripture where Abram veers from God's will a bit and how God redeems him.  

Blessings
Have you ever felt like everything just goes wrong, one thing after another?  Are you ready to see God bless your life, your family and/or career?  Everyone of us will have many hiccups along this road called life, but we can have a blessed life.  We see this in God's promise to Abram.  If you want a blessed life from the Lord, then obey His Word and walk in Christ. But remember the first point.  If you are obeying God and walking in Christ and things seem to be breaking one thing after the other, then refer back to the point on pruning.  God may be taking you through a phase to take away the parts that are not bearing fruit.  

Terah’s Descendants

27Now these are the generations of Terah. Terah fathered Abram, Nahor, and Haran; and Haran fathered Lot. 28Haran died in the presence of his father Terah in the land of his kindred, in Ur of the Chaldeans. 29And Abram and Nahor took wives. The name of Abram’s wife was Sarai, and the name of Nahor’s wife, Milcah, the daughter of Haran the father of Milcah and Iscah.30Now Sarai was barren; she had no child.

31Terah took Abram his son and Lot the son of Haran, his grandson, and Sarai his daughter-in-law, his son Abram’s wife, and they went forth together from Ur of the Chaldeans to go into the land of Canaan, but when they came to Haran, they settled there. 32The days of Terah were 205 years, and Terah died in Haran.

Here begins the story and introduction of Abram and Sarai. God has not yet changed their names to the well know Abraham and Sarah of the Bible stories.  Haran, the son of Terah, and the brother of Abram died, but had a son named Lot.  Terah, Abram, Sarai and Lot went away from Ur of Chaldeans (an idolatrous land) to Canaan but stopped and settled in Haran.  Terah died in Haran. Haran is about midway between Ur and Canaan.
