The function and instruction that sets the doctrinal teaching and learning process in order, is called doctrine. This doctrine is induced by a delegate and ambassador of the Gospel of Jesus Christ, with miraculous power sent to eradicate heresy and establish the truth. The Truth is a Person, the Lord Jesus Christ.
For I will be merciful to their unrighteousness, and their sins and their lawless deeds I will remember no more.” In that He says, “A new covenant,” He has made the first obsolete. Now what is becoming obsolete and growing old is ready to vanish away.
The most faithful reminder is the Holy Spirit who brings to your remembrance all that Jesus said.
John 14:26 But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all things that I said to you.
We all need a guide. Yes the Holy Spirit is our ultimate guide. But who introduced you to the Holy Spirit? Paul the apostle speaks about remembering what you have learnt and from whom you have learnt it. He also encourages his disciples to do the things that they learnt, received, heard and saw him do. Imitate me as I imitate Christ.
In the New Testament every Apostolic Epistle starts with an Apostolic Blessing or greeting: ‘Grace & Peace to you!’ The reason why the Apostles did that was because they pronounced the Aaronic Blessing on believers! They knew what they were doing and the people understood it too. It is not just a lame religious exercise, but it is a powerful blessing for those who believe!
Because we are forgiven and risen with Christ we put off the old man of sin & selfish living and put on the new man that is made in the image of Christ Jesus (Col 3:5-17) and it has a positive, holy influence on all our relations (Col 3:18-25) We are a new species of being in Christ. We learn to make Him pre-eminent in everything we do or say and He takes care of so many things we think we have to take care of. We cast our cares on Him for He cares for us.
