All He asks is that we ask for it - and seek earnestly. Wisdom is knowledge. The wise are those who know. But although wisdom is knowledge, not all knowledge is wisdom. Knowledge by itself does not guarantee wisdom.
Wisdom is a perfect knowledge.
This fact tells us immediately that in knowledge there are degrees of perfection. When we have the Faith, and we thank God if we do, we know some tremendous truths - e.g. the truths we proclaim in the Apostles Creed which we recite daily to start the Rosary. We know these truths with absolute certainty, and yet the knowledge of Faith is not as perfect as the beatific knowledge of the blessed in heaven. It is said of St. Teresa of Avila, to take one example, that she almost had the Beatific Vision, that in her mystical life there remained just one thin veil keeping her knowledge of Faith from becoming the full and perfect knowledge of vision. Wisdom is the most perfect knowledge of the most important truths.
