Gentleness - appropriate to actions, where meekness is a condition of mind and heart
"Meekness manifested by the Lord and commended to the believer is full of power.
The common assumption is that when a man is meek it is because he cannot help himself;
but the Lord Jesus was meek because He had the infinite resources of God at His command.
Described negatively, meekness is the opposite to self-assertiveness and self-interest;
it is equanimity of spirit that is neither elated nor cast down, simply because it is
not occupied with self at all.
FromVine's Expository Dictionary

Submission - to give in to another's will. In horse terms we say "on the bit" or
"give to the bit", meaning that the horse accepts the control/direction of the rider.
By submitting, the horse allows the rider to help "collect" or "round his frame" to
be able to do things he couldn't do without that collection. The horse in this image
is a good example of collection.

Self Control - one of the Fruits of the Spirit (Galatians 5:23), it is self restraint,
not acting on impulse or 'reflex'. A horse so trained and submitted that
even when presented with a startling situation does not 'spook' or run, which is
his natural reaction to danger. Trust is so high that fear has no place in his repertoire.

Who is more likely to be given great responsibility, the selfish, out-of-control
person or the one who has learned the rules and makes wise decisions based
on past experience, the one whose desire is success of the mission, not personal fame?

Moses was said to be the meekest person in the Old Testament. Think about all the things he accomplished by submitting to God's direction! You remember that he tried to lead the Israelites in his own power and ended up killing an Egyptian and then running away into the desert. Yet, when he did what God told him to, he performed miracle after miracle for the benefit of a people who continually rebelled against their God. They were a 'stiffnecked' people - not the submitted, supple-necked people God desired.

Jesus Christ was totally submitted to the will of His Father. He, after all, was God, too,and could have blasted His way through instead of submitting to the Father's plan. Imagine God stuffing Himself into a little baby's body! And it goes on from there!

Yes, the Meek Will Inherit the Earth! Why? Because God can trust them - they want
what He wants. They are willing to submit to His control for His common good.
They know that His plans for them are better than anything they could
possibly attain for themselves. They know God loves them far more than can
ever even be imagined (Ephesians 3:17-19).

Therefore:

If by the Holy Spirit we have our life in God, let us go forward Walking in line
keeping in step, our conduct controlled by the Spirit. Galatians 5:25 AMP

Press on toward the goal to win the supreme and heavenly prize to which God
in Christ Jesus is calling us. Let us hold true to what we have already
attained and walk and order our lives by that. Philippians 3:14, 16

On the Bitis an excellent short article explaining how the horse uses his body differently, submitting to the rider's suggestions through the reins. The reins are truly 'aids' and not 'rules'. The horse accepts the help of the rider, rather than being forced into submission.
As you read, reflect on how this can be applied to yourself spiritually.
