The Word of His Power

"And He is the radiance of His glory and the exact representation of His nature,
and upholds all things by the word of His power."
Hebrews 1:3

The purpose of disciplining a child is to teach them there is power backing up words. Kids need to know this at the very core of their being in order to have a strong faith in God. When your child does something and you tell him not to do it, you have used a word of authority to give him a command. If he disobeys, you remind him with your word of authority. However, if he chooses to continue to disobey even though he knows what you've said, then you back your words with physical power. Using your physical strength to stop him, even the rod of correction if necessary. Not abuse of course, but using your greater physical strength to show him that there is a power that backs your words. God designed it this way so children will learn this while they are young--before they have an equal or greater amount of physical strength than the parents.

"But let your statement be, 'Yes, yes' or 'No, no'; anything beyond these is of evil." 

Matthew 5:37

By consistently enforcing your words, your child will learn the power of words, and ultimately, the power of the Word of God. This is vital.

"For this reason we must pay much closer attention to what we have heard, so that we do not drift away from it. For if the word spoken through angels proved unalterable, and every transgression and disobedience received a just penalty, how will we escape if we neglect so great a salvation? After it was at the first spoken through the Lord, it was confirmed to us by those who heard. God also testifying with them, both by signs and wonders and by various miracles and by gifts of the Holy Spirit according to His own will." Hebrews 2:1-4

God "testifies" with the Word that is preached by signs, wonders, miracles and gifts of the Spirit. He reveals the power of His Word, the authority of His Word through the display of His power. This reveals His authority over all. It reveals that He is the Most High--the One deserving of all worship. Children will be better able to believe if they have an understanding of this whole concept of the power of words.
