Psalm 32:8 I will instruct you and teach you in the way you shall go. I will guide you with My eye.
Psalm 32:9 do not be as the horse, or as the mule, which have no understanding: whose mouth must be held in, or harnessed with bit and bridle, else they will not come near you.
God covenanted to instruct us and to teach us the way we should go; He wants to guide us  with His eye. Many times believers will think, because it looks good and sounds good, that it must be from God. If we do not see with the eye of God, and hear what God is saying concerning our situation; we may end up suffering losses. It is not in God’s heart that any  of His children should suffer any destruction at all.
Unfortunately many believers are like horses, and mules. They do not have the
understanding of the ways of God only the act of God (Psalm 103:7). God does not
want us to be ignorant of his ways. But how can we know the ways of God? The bible
tells us: my people are destroyed or perish for lack of knowledge, because they have
rejected knowledge (Hosea 4:6). God wants to instruct us and teach us His ways
and guide us with his eye.
The truth is: if we do not have the knowledge of the ways of God, and do not see with His eye, we are just like a blind  man leading another blind man; we all will  fall into a ditch (Matthew 15:14). God sees in the spirit realm and in the physical realm, furthermore He knows the end from the beginning (Isaiah 46:10). We on the other
hand only see in the physical realm, and do not even know what will happen the next
second.
Many believers will only seek God’s  guidance when they have fallen into a
ditch. They are like the horse and the mule that need the bit and the bridle to obey
God. Brethren, let us not fall into that category of believers, but instead let us
learn the ways of the Lord. A believer, who only knows the acts of God, will not be a
strong believer, for he does not know how God performed those acts. Most likely he will be unable to have God move on his behalf next time. But if he knows the ways of God, he understands what moved the heart of God, to act on his behalf the first time, so he can advise other people, and they can also receive the same breakthrough from the Lord.
