The Preaching of the Gospel

"In order that people may be brought to faith, God mercifully sends proclaimers of this very joyful message to the people he wishes and at the time he wishes. By this ministry people are called to repentance and faith in Christ crucified. For how shall they believe in him of whom they have not heard? And how shall they hear without someone preaching? And how shall they preach unless they have been sent? (see Rom. 10:14-15)"  - from The Canons of Dordt, Article III

The cleverness of man is not the means by which God has chosen to save, it is by the PREACHING OF THE GOSPEL!

Where is the one who is wise? Where is the scribe? Where is the debater of this age? Has not God made foolish the wisdom of the world? 21 For since, in the wisdom of God, the world did not know God through wisdom, it pleased God through the folly of what we preach to save those who believe.  (1 Corinthians 1:20-12 ESV)

When it comes to the matters of spiritual life and conduct and ministry, is the Bible sufficient or do we need psychology and human wisdom?

Not that we are sufficient in ourselves to claim anything as coming from us, but our sufficiency is from God  (2 Corinthians 3:5 ESV)

And we impart this in words not taught by human wisdom but taught by the Spirit, interpreting spiritual truths to those who are spiritual.  (1 Corinthians 2:13 ESV)

The Bible is clear that we are reborn by the Word of God, not by man.

since you have been born again, not of perishable seed but of imperishable, through the living and abiding word of God  (1 Peter 1:23 ESV)

When you resort to schemes in order to draw people to God, that reveals that you do not trust in the power of God's Word to convert the soul (Psalm 19:7) and that you think God needs your help.

Sola Scriptura... Soli Deo Gloria...
