Yes by faith Abe obeyed the voice of God.
GENESIS 26 [3] Sojourn in this land, and I will be with thee, and will bless thee; for unto thee, AND UNTO THY SEED, I will give all these countries, and I WILL PERFORM THE OATH WHICH I SWARE UNTO ABRAHAM thy father; [4] And I will make thy seed to multiply as the stars of heaven, and will give unto thy seed all these countries; and in thy seed shall all the nations of the earth be blessed; [5] BECAUSE THAT ABRAHAM OBEYED MY VOICE, and kept my charge, MY COMMANDMENTS, my statutes, and MY LAWS.
Honest Abe heard Gods "voice" and so he kept His commandments
JOHN 10 [27] MY SHEEP HEAR MY VOICE, and I know them, and they follow me: [28] And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.
Also Gods sheep hear His “voice”.
DEUT. 27 [8] And thou shalt write upon the stones all the words of this law very plainly. [9] And Moses and the priests the Levites spake unto all Israel, saying, Take heed, and hearken, O Israel; this day thou art become the people of the Lord thy God. [10] Thou shalt therefore OBEY THE VOICE of the Lord thy God, and DO HIS COMMANDMENTS and his statutes, which I command thee this day.
DEUT. 4 [12] And the Lord spake unto you out of the midst of the fire: ye heard THE VOICE of the words, but saw no similitude; only ye heard a voice. [13] And he declared unto you his covenant, which HE COMMANDED YOU TO PERFORM, EVEN TEN COMMANDMENTS; and he wrote them upon two tables of stone.
It is truly Gods 10 commandments
While it is said, TO DAY IF YE WILL HEAR HIS VOICE, HARDEN NOT YOUR HEARTS
