I'm sure there would be more we could do as Christians. Love more, give more, feed the hungry, search the word.
As a nation we have Evangelized the world and the first to help out.
God has blessed us to do so, and the technology through the years, the engineering has been like none other.
But the world is fixed in their heart the scriptures say.
As you know there is nothing wrong with the gospel, the message men give off about the gospel can become twisted but you cannot change the gospel.
The scripture that I thought about is in 1 Cor. 2:5-9,
5 That your faith should not stand in the wisdom of men, but in the power of God.
6 Howbeit we speak wisdom among them that are perfect: yet not the wisdom of this world, nor of the princes of this world, that come to nought:
7 But we speak the wisdom of God in a mystery, even the hidden wisdom, which God ordained before the world unto our glory:
8 Which none of the princes of this world knew: for had they known it, they would not have crucified the Lord of glory.
9 But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him.
Understanding who the princes of this world are? They were the religious leaders of Jesus day. The same thing operates today. There is a wisdom that only the Father gives, Paul said it is hidden from the minds of men.
Religious leaders today have the same problem as has always existed, they can only take a believer so far.
Preachers, teachers so forth are ordained of God, some are good and some not so good, doesn't matter.
Look at the good, they, as good as they are, can only take a believer so far. It takes the HolySpirit to reveal the things of God to an individual.
So there remains, for the believer, the hidden mystery of God to be revealed. In the mystery of God is the wisdom of God.
