For God did not send his Son into the world to condemn the world, but to save the world through him.
~John 3:17
Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them.
~Matthew 5:17
When you get to know Jesus, everything changes. See, before Jesus and after the fall in the Garden of Eden (Genesis 3), mankind was living under the "law" alone, which defined morality and godly character.
The Old Testament of the Bible is full of accounts of mankind's failed attempts at holiness and destructive behavior. That is not to say all people in the Old Testament were corrupt, but people in general were. There were procedures to cleanse people from their sin which can be studied in Leviticus in the Old Testament.
The Father God sent messengers and signs to people to get them to change and they just didn't. However, this did not catch God by surprise. He knew man's pride would get in the way and they would become self-righteous and prideful. So, there were many prophecies that spoke of the coming Messiah, Jesus, who would come to save us from our self-destruction. Jesus's conception, birth, ministry, death and resurrection were the fulfilment of those Prophecies. Now, we have the gift of His Holy Spirit to guide and watch over us in this lost and dying world. As His children who have accepted His Son, we are empowered to live lives of victory and freedom over sin and darkness.
The benefit to being His child walking in this New Destiny is that victory and freedom and the opportunity we have to share this Good News with others!
If my testimony or your testimony helps one person walk in victory and secure their eternal position in Heaven, it's worth it to take the time to share!
We have seen the sick healed, people with addictions delivered and even set free from demons! That's the destiny of a believer! You can read about these in what is referred to as "The Gospels": Matthew, Mark, Luke and John in the New Testament.
