The thief comes not, but for to steal, and to kill, and to destroy. I have come that they might have life. And they they might have it more abundantly.
Look at the last bit of this scripture. It is telling us that we are first class citizens of heaven. Never mind what the world may think of us. We are not to live a life in fear or a second rate life.
Abundantly? as we immerse ourselves in the word of God. So we shall walk into the abundance of the word of God. That will mean for us to walk in the promises there. Take a read and you will find an abundance of them.
There is also a warning in Romans 12. verse 2.
And do not be conformed to this world, but be transformed by the renewing of your minds. That you may prove that which is good, and acceptable, and perfect will of God. We are being advised to not think as the world does. But to come in line with the perfect will of God.
That is the way to be in line with the word of God. Who helps us? the Holy Spirit, we must not try to out think him. That is the way of the world.
