The meek ... shall increase their joy in the Lord, and the poor among men shall rejoice in the Holy One of Israel. — Except ye be converted, and become as little children, ye shall not enter into the kingdom of heaven. Whosoever therefore shall humble himself as this little child, the same is greatest in the kingdom of heaven. — The ornament of a meek and quiet spirit, ...is in the sight of God of great price. — Charity vaunteth not itself, is not puffed up.
Follow after meekness. — Take my yoke upon you and learn O me, for I am meek and lowly in heart. — He was oppressed, and he was afflicted, yet he opened not his mouth: he is brought as lamb to the slaughter, and as a sheep before her shearers is dumb so he openeth not his mouth. — Christ also suffered for us, leaving us an example, that ye should follow his steps: who did no sin neither was guile found in his mouth: who, when he was reviled reviled not again, ... but committed himself to him that judgeth righteously.
The closest word we have to fit what's here translated "meekness" is "gentleness;" that doesn't really convey the entire meaning, though, because there is simplicity, gentleness, acceptance, love, and submission conveyed by the term; so if you say, "Blessed are the meek," you are saying that such a person is not only gentle and unassuming, but that he is not full of resistive pride, and that he is simple, in the sense he doesn't need to be evasive or deceptive. This is an integral part of the Christian's inner self, if he is allowing the Spirit full and free reign within him. How to be like this? first, LISTEN to the Spirit as He ministers to your heart. He will guide you in the way of gentleness; second, MEDITATE on the verses above. They will give you a better understanding of the way of gentleness. Third, STUDY: you can google the words meekness in KJV for the locations, or use a KJV concordance, but remember, other translations handle the underlying Greek word differently. It's easier, of course, to just read what you see above, and put it into practice than to do all that study; and perhaps just as effective.
