But you, beloved, building yourselves up on your most holy faith, praying in the Holy Spirit.
Jude 20 (NKJV)
All believers, regardless of their origin, have one thing in common: their faith in Christ. It is this commonality that constitutes the very foundation of our salvation. Some may be more spiritual than others or know the Bible better, but that doesn't mean we are like professionals, each operating in his own circle of activity. For example, some work in one field like Accounting or IT, and others in another, like medicine or law.
In a church you may find people of different social ranks or different levels of intelligence. The only way to overcome these differences is to show love and compassion. It is on the basis of this truth that Jude thus exhorts us, telling us to build the foundation of our most holy faith which is Jesus Christ. In this sense, he asks us to support one another, to pray for one another, to encourage one another and to come to the aid of those in need.
Even Paul in his letter to the Ephesians exhorts us thus: "As a prisoner for the Lord, then, I urge you to live a life worthy of the calling you have received. Be completely humble and gentle; be patient, bearing with one another in love. Make every effort to keep the unity of the Spirit through the bond of peace. There is one body and one Spirit, just as you were called to one hope when you were called." (Ephesians 4:1-4 / NIV).
May the grace of God be with you all.
