Question

what mathematical principles can we draw from Ephesisians 4:14-15 and Deuteronomy 32-4

Answer 1

Ephesians 4:14,15

^"14 Then we will no longer be infants, tossed back and forth by the waves, and blown here and there by every wind of teaching and by the cunning and craftiness of people in their deceitful scheming. ¹⁵ Instead, speaking the truth in love, we will grow to become in every respect the mature body of him who is the head, that is, Christ."

We should be constant in everything that we do in Christ. Don't act as some non differentiable functions which moves in one way at a time, then entirely different direction at another... Whose tangents will cross each other and others doubt the direction of which we travel. Christianity is a path.. (Mat:7:13) and others consider it as something wrong by our diverting stand each time. To avoid this and make our rate of growth faster, the elders are appointed in the church.( Ephesians 4:11). So that we can reach the destination of growing up to the head of Jesus much faster.

There are different areas where we are to grow up to Him. We should be uniform in growing upto the head of Christ in all those aspects.

Deuteronomy 32:4

He is the Rock, his works are perfect,
    and all his ways are just.
A faithful God who does no wrong,
    upright and just is he.

Like perfect numbers, everything that tries to divide it will add up to give the rock..Jesus is the rock . There are many differences in different Christian denominations. But there are a few remnant everywhere within these different views who adds up to form the body of Christ in these days.

After all Bible is Spiritual...not Mathematical.

It is not revealed for wise and intelligent, but babes. (Mat 11:25) So be careful...
