1 John 3:14
We know that we have passed out of death into life, because we love the brethren. (Fellow Believers in Christ) He who does not love abides in death.
Galatians 6
:10 As we have therefore opportunity,
let us do good unto all men,
Especially unto them who are of the household of faith.
Ephesians 2
:19 Now therefore ye are no more strangers
and foreigners,
but fellowcitizens with the saints,
and of the household of God;
:20 And are built upon the foundation of the apostles
and prophets,
Jesus Christ himself being the chief corner stone;
:21 In whom all the building fitly framed together
groweth unto an holy temple in the Lord:
:22 In whom ye also
are builded together
for an habitation of God through the Spirit.
We are no longer as the Gentiles were--strangers and foreigners but fellowcitizens with the saints and of the household of God. We are the building where Christ is the chief corner stone. The household becomes the temple for God to live in and manifest Himself through. We are His habitation and the household that grows unto a holy temple in the Lord.
Now that we have identified who is the household, how are we to be especially good unto them (us)?
Take care of one another, help the more spiritually immature ones.
Romans 15
:1 We then that are strong
ought to bear the infirmities of the weak,
and not to please ourselves.
:2 Let every one of us please his neighbour
[the context is brethren--those of the household]
for his good to edification.
:3 For even Christ pleased not himself;
but, as it is written,
The reproaches of them that reproached thee fell on me.
We are to be likeminded one toward another. No divisions, come together on the Word of God, receive each other to the glory of God.
:5 Now the God of patience
and consolation
grant you to be likeminded one toward another
according to Christ Jesus:
:6 That ye may with one mind
and one mouth
glorify God, even the Father of our Lord Jesus Christ.
:7 Wherefore receive ye one another,
as Christ also received us to the glory of God.
Receive one another no matter if they are rich, poor, a different race, your own brother, your own sister, your in-laws. Are they of the household of faith? Receive them. That is the Word.
Acts 2
:44 And all that believed were together,
and had all things common;
:45 And sold their possessions and goods,
and parted them to all men,
as every man had need.
:46 And they,
continuing daily with one accord in the temple,
and breaking bread from house to house,
did eat their meat with gladness
and singleness of heart,
:47 Praising God,
and having favour [charis-grace] with all the people.
And the Lord added to the church daily
such as should be saved.
The word favour is the Greek word charis--grace. Strong's Analytical Concordance defines it as:
the merciful kindness by which God, exerting his holy influence upon souls, turns them to Christ, keeps, strengthens, increases them in Christian faith, knowledge, affection, and kindles them to the exercise of the Christian virtues
