God has established a specific plan for His church. It is outlined throughout His word. When reading the old testament, you can see that it was a pattern or a shadow of the fulfillment of God’s word as outlined in the new testament. Apostle Paul tells us to take heed to those things written of old so that we don’t make the same mistakes resulting in missing out on the promises of God.
Wherefore let him that thinketh he standeth take heed lest he fall. 1 Corinthians 10:12
When we are born again into the newness of Christ Jesus, we no longer use the world as our standard for living, we use the word of God. His stardard is so far removed from the world; it as as different as night and day. It is because of this that our light for Jesus shines into the darkness of the world and we are able to draw people to Christ or repel those that are too far gone with the enemy. We have the example of the children of Israeal to learn from and to understand what happens when we do not follow the pattern establishe by God through His word.
The prophet Ezekiel told the people to look at God's pattern and measure the pattern of their lives accordingly:
Wherefore the Lord said, Forasmuch as this people draw near me with their mouth, and with their lips do honour me, but have removed their heart far from me, and their fear toward me is taught by the precept of men: Isaiah 29:13
A Biblical pattern is a spiritual model or example given in Scripture for purposes of imitation. For example, the life of Jesus Christ is given as a pattern or model which believers are to follow.
A Biblical principle is a spiritual truth taught in Scripture. Such principles often incorporate underlying principles which apply to many different situations. For example, one Biblical principle taught by Jesus is "Give and ye shall receive." Its subordinate truths apply to giving money, material goods, friendship, etc. In each of these, spiritual benefits are received as a result of the act of giving.
'For we dare not make ourselves of the number, or compare ourselves with some that commend themselves: but, they measuring themselves by themselves and comparing themselves among themselves are not wise. 2 Corinthians 10:12
For not he that commendeth himself is approved, but whom the Lord commendeth. 2 Corinthians 10:18
All this, said David, the Lord made me understand in writing by his hand upon me, even all the works of this pattern. (1 Chronicles 28:19)
Brethren, be followers together of me, and mark them which walk so as ye have us for an ensample.
Therefore leaving the principles of the doctrine of Christ, let us go on unto perfection; . . . (Hebrews 6:1-2)
