If we could live our lives without lying, we could probably live our lives without committing other sins. Why would God send Jesus if that was the case. Point made.
This is, more or less, why we sin.
We once could live our lives without lying. We once lived our lives free from the bondage of sin.
At some point, however, Satan, who was formerly Lucifer, one of the three Archangels of Heaven, became haughty due to his wisdom and perfect beauty. The three Archangels were Michael (Jesus Christ), Gabriel, and Lucifer (Satan). - Rev. 5:11
These three Archangels each were incharge of a third of Heaven's Angels.
Inequity (lawlessness) was found in Lucifer - he had gradually become corrupt, and he believed he was deserving of God's throne and rulership. He therefor decided to attack God with his third of the Angels, whom he must have corrupted, in an attempt to seize Jehovah's throne. This took place to the North of Heaven, over the "empty place". Job 26:7
This failed, however, and Lucifer, now known as Satan the Devil, was hurled to the Earth with his third of the Angels, who themselves had become corrupt, wicked. They more or less became Demons. Wicked Spirits. Ezekiel 28:15-16
Satan was thrown to the Earth for the kings of the world to behold. Ezekiel 28:17
Satan has corrupted the Earth, having since tempted Eve to eat of the tree of the knowledge of good and bad.The wages sin pays is death. Romans 6: 1-23 This is why we sin, and die. This confirms our personal corruption.
To lie is to sin. Our parents, Adam and Eve once lived perfect lives in the Garden of Eden, but fell to temptation, inwhich Eve sinned, then caused Adam to sin, and again, through sin comes corruption and death.
We lie, Romero, because we are corrupt. We sin often because we are imperfect. Jesus had to come down and sacrifice Himself and shed his precious blood to atone for our sins, so we could be reconciled to Christ, and Jehovah God, and attain perfection once again, which we had lost.
God entrusted Adam and Eve to multiply and be fruitful in the world, so that they could create a holy Government on Earth. We would of had perfect lives.
We lost our perfection, because we were tempted by Satan when he was thrown to Earth. Satan and his wicked Angels desired to overthrow God's Government on Earth, and they succeeded, because Adam had lost his perfection.
Adam back then was perfect, and if he had been willing to obey God's instructions, he could have qualified to replace Satan and his future Government(s) and restore God's Government.
Once Adam & Eve were tempted/sinned, Adam lost his perfection and he could no longer qualify to restore God's Government, which would most likely prevent Satan overthrowing God's Government on Earth, and we of course, would have remained perfect, as you assumed we are.
In order to regain our perfection, a sacrifice of great value had to be made. This was the ransom sacrifice of Jesus Christ, our King. This sacrifice would save those who chose to live God's way, despite our struggles with temptation & imperfection, and through Christ, God would save obedient mankind, but would destroy those who continued to live the Devils way of life - Continually sinning and doing what is wrong and unholy in God's own eye's.
" believe in the Lord Jesus and you will be saved " Acts 16:31
" and as many as had been appointed to eternal life, believed." Acts 13:48
But the nations became wrathful, and your own wrath came, and the appointed time for the dead to be judged, and to give [their] reward to your slaves the prophets and to the holy ones and to those fearing your name, the small and the great, and to bring to ruin those ruining the earth. Rev 11:18
