It is expected for the kid to behave like the father goat; the kitten like the cat; the puppy like the dog; the chicks like the mother hen and the cub like a lion.
Contrary to this is an abnormality. An eaglet shouldn't behave like a dog neither should a fish fly like an eagle.
For you to define "a son", it means that there exist (or once existed) a father.
This illustrations introduces us into our topic - Manifesting our Sonship in Christ and walking in His Fullness.
WE ARE THE CHILDREN OF GOD
The Symbiotic relationship in introductory part of this article describes our relationship with our father.
Genesis 1:27 So God created man in his own image, in the image of God created He him; male and female created He them. (KJV)
We share the same image with God and as well, were made in His alikeness.
Unfortunately, our first parents fell. They fell into sin and lost this divine relationship. For the Father to prove His love towards us, He sent His only begotten Son to die for us even when we were yet sinners, that those who believe in Him shall be saved.
MANIFESTING THE FULLNESS OF CHRIST
This reconciliation is spiritual and is attained by Faith. We can only manifest what we believe. The Bible says "Be it done unto you according to your Faith".
Romans 8:14 For as many as are led by the Spirit of God, they are the sons of God.
The eagles can't fly without the wings. Similarly, we cannot manifest the Fullness of Christ without being possessed by His Spirit.
LIVING WITH THE CONSCIOUSNESS
Let's look at Colossians 1:9 in the Amplified version.
For this reason we also, from the day we heard of it, have not ceased to pray and make [special] request for you, [asking] that you may be filled with the full (deep and clear) knowledge of His will in all spiritual wisdom [in comprehensive insight into the ways and purposes of God] and in understanding and discernment of spiritual things--
We who are in Him, having been made full have come to the fullness of life. Without the Spirit we are empty and fruitless.
The Psalmist says "I will look up to the heavens and as a servant depends on his master, so will he look up to God".
We have to allow this Davidic declaration to flow regularly in our consciousness. This is an invitation to live in the consciousness of the fact that He has made us whole. He is the foundation of the new covenant, the hope of our glory.
In conclusion, Paul went further to say in the The book of Romans 8:19
For the earnest expectation of the creature, (the world) waiteth for the manifestation of the sons (and daughters) of God.
Therefore, let's have our eyes fixed on Him, so that we can grow victoriously.
