Solomon awoke from his dream and immediately sacrificed to the Lord in Jerusalem. Again, Solomon is responding physically to a promise he would soon see fulfilled physically. At this point, however, his response is based solely on faith.

This combination reminds me of how we are saved . . .

That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. Romans 10:9-10

It is through the unseen belief of the heart coupled with the spoken word of the mouth that salvation is brought to the sinner. And the same is true throughout our Christian walk, for true faith is inevitably linked to outward manifestation.
