“So you my son, be strong (strengthened inwardly) in the grace (spiritual blessing) that is [to be found only] in Christ Jesus.”  2 Timothy 2:1
The Amplified Bible

This ‘grace, spiritual blessing’ can only be found in our living relationship to Jesus Christ.  

Scripture tells us,
“For you are all sons of God through faith in Christ Jesus.”  Galatians 3:26

And in Romans 8:29,
“For whom He foreknew, He also predestined to be conformed to the image of His Son, that He might be the firstborn among many brethren.”  

We are livingly related to Christ.  Since this is so and we are one in 
Christ and are of the family of God, we are related to one another.

Concerning our spiritual relationship--
*Obedience secures the benefits:
Read the example in Luke 8:19-21 when Jesus’ mother, Mary and His brothers (and His sisters as mentioned in Matthew’s account 12:46-50), came to speak to Him,
“But He answered them, ‘My mother and My brothers are those who hear the word of God and do it.’”  Luke 8:21
Did you catch that?  Those who hear the word of God and do it.

*All barriers are broken down:
“Therefore you are no longer outsiders (exiles, migrants, and aliens, excluded from the rights of citizens), but you now share citizenship with the saints (God’s people, consecrated and set apart for Himself); and you belong to God’s [own] household.”  Ephesians 2:19 The Amplified Bible

*Saints in heaven and on earth are united in this spiritual relationship:
The Apostle Paul , writing to the Ephesians, says,
“For this reason, I bow my knees before the Father, 
from whom every family in heaven and on earth derives its name.”  Ephesians 3:14-15

*Jesus makes known this spiritual relationship:
“For He who sanctifies and those who are sanctified all have one source. That is why He is not ashamed to call them brothers (and sisters).
Hebrews 2:11

How awesome is the love of God to us that He would make all provisions to draw us into His own family.  The prayer of Jesus in John 17 never ceases to be astounding.  (Please read it.)  The following are only a few verses where Jesus not only  prays for His disciples, but for all who will believe through their word.

“I do not ask for these only, but also for those who will believe in Me through their word,
that they may all be one, just as You, Father, are in Me, and I in You, that they also may be in Us, so that the world may believe that You have sent Me.
The glory that You have given Me I have given to them, that they may be one even as We are one
I in them and You in Me, that they may become perfectly one, so that the world may know that You sent Me and loved them even as You loved Me.”
John 17:20-23

What joy is ours in Christ Jesus, The Savior ! The Lord!  It just makes you want to sing!
“Break forth into joy oh my soul,t
 Break forth into joy oh my soul,
 In the presence of the Lord there is joy forevermore.
 Break forth, break forth into joy oh my soul.”
Blessing to all.  Amen
