Thanks very much for finding the link for me Heartsong.
Smokey all that have been born again of His Spirit are called indeed, you are correct.
Not all us are called in the same fashion and I would venture to say WE TODAY have many different callings, just not as Paul, and as Notme indicated. Even today, some are called to preach verbally, as well as sanctification living as a sermon. Sanctified living is a sermon. God not only loved us enough to send Jesus his only Son to die on the cross and call disciples to follow, but raised HIM from the dead, and he continued to call the Apostle Paul, a man who was against the cause of Christ, just to show to the world HIS power. Then Jesus indwelt Paul with the Holy Spirit and anointed and authorized Paul to write these words to guide our paths. The same, Holy Spirit that Jesus indwelt Paul with is the same HE gave us, the same spirit for understanding the words that Paul wrote. Us and Paul are speaking in tongues and interpreting. The world don't understand it and it is foolishness to them. We don't understand it all, but just as he told the disciples when he was with them, I have much more to tell you but you could not bear it now.
John 16:12-14
12 I have yet many things to say unto you, but ye cannot bear them now.
13 Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come.
14 He shall glorify me: for he shall receive of mine, and shall shew it unto you.

Could being born miraculously by His Spirit and these words from the Holy Scriptures be what Jesus was referring to in that passage?
But one day we will.
1 Cor 2:9-3:1
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.
10 But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God.
11 For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God.
12 Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God.
13 Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual.
14 But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned.
15 But he that is spiritual judgeth all things, yet he himself is judged of no man.
16 For who hath known the mind of the Lord, that he may instruct him? But we have the mind of Christ.

Abraham's life was a sermon, as he gave back to God and said "the Lord will provide". God did provide for Abraham, even though Abraham was impatient in waiting for the promise. Abraham gave back to God 10% of what God gave him with a thankful heart, hundreds of years before God gave the law to Moses. Some say giving to God came through the law. Not so. Giving came in thankfulness to the promise.
