Words spoken to/about a person or thing carry one of these two natures-it is either a truth or it is a lie.
Also, there are many who speak to/about a person or a thing. God speaks, Satan speaks, man speaks, the environment speaks, nature speaks, science speaks etc.
And in most cases, all these voices are in conflict with one another, contradicting one another. Could all of them be the truth or could all of them be a lie? Certainly not. Then who is telling the lie?
The Bible says: " And ye shall know the truth, and the truth shall make you free." John 8:32. Your freedom from any form of assault is determined by your knowledge of the truth. Until you know the truth you will always believe a lie which in turn keep you in bondage, limitations, fear, agony, bad mood etc.
For instance, God by His word says you are blessed and wealthy but Satan by the lack of the physical wealth at your disposal at the moment, says you are poor and the people around you and circumstances surrounding you say the same thing.
Could all of them be saying the truth or could all of them be lying? That's not possible. One must be lying while the other telling the truth. But who then is lying?
Romans 3:4 says "God forbid: yea, let God be true, but every man a liar......"
This means that wherever/whenever there is a contradiction between God's word and man's (physical instinct and analysis) word, God is the One telling the truth and man is the liar.
Hebrews 6:18 says "That by two immutable things, in which it was impossible for God to lie, we might have a strong consolation, who have fled for refuge to lay hold upon the hope set before us."
It is impossible for God to lie. Reject the lie of the devil concerning your life, family, marriage, studies, business, friends, home, health, wealth etc. Hold on to God's infallible words.
Have men said that you can never make it in life, it is a lie; have they said that you cannot give birth, it is a lie; have they said that you cannot be healed of that ailment, it is a lie; have they said that and that, they are all lies.
Don't give up brother, don't lose faith sister, don't commit suicide Sir, don't stop making attempt madam, your time of celebration is near. Don't accept the lies and deceit of the devil and of men.
Let GOD be TRUE and EVERY MAN a LIAR.
Faithful is He that promised, He shall surely bring it to pass.
