By Faith

Heb 11:8  By faith Abraham, when he was called to go out into a place which he should after receive for an inheritance, obeyed; and he went out, not knowing whither he went.

Abraham “did not know where he was going” it simply was
enough for him to know he went with God. 

He did not lean as much on the promises as he did on the Promiser.

And he did not look at the difficulties of his circumstances but looked to His King the eternal, limitless, invisible, wise, and only
God who had reached down from His throne to direct his path and who would certainly prove Himself.
 
O glorious faith! Your works and possibilities are these: contentment to set sail with the orders still sealed, due to unwavering confidence in the wisdom of the Lord High Admiral;
and a willingness to get up, leave everything, and follow Christ,
because of the joyful assurance that earth’s best does not compare with heaven’s least. 

~F. B. Meyer~

In no way is it enough to set out cheerfully with God on any
venture of faith.You must also be willing to take your ideas of
what the journey will be like and tear them into tiny pieces, for nothing on the itinerary will happen as you expect.
 
Your Guide will not keep to any beaten path. He will lead you through ways you would never have dreamed your eyes would see.

He knows no fear, and He expects you to fear nothing while He is with you.
