1 Corinthians 12:13
For by one Spirit we were all baptized into one body—whether Jews or Greeks, whether slaves or free—and have all been made to drink of one Spirit.
There are two essential events that befall all believers at rebirth and thereafter. First, all of us are admitted into the Body of Christ by one Holy Spirit. That means we no longer exist outside Christ. We have no life anywhere else. In Him we live move and have our being.
Such a knowledge must affect how we view and treat one another. Our awareness of our location in Christ together must affect our attitudes and conduct. Even mean-spirited folks do their utmost to behave with dignity in certain environments. How much more should it be with the redeemed of the Lord!
Thank God that we don’t get to choose who is admitted into the Body of Christ, for our biases would likely disqualify many potential saints. Now we know that as every believer was divinely handpicked as it were, we cannot reject any whom God has chosen!
Second, all true believers drink from the same spiritual fountain (see also John 7:37-39). Indeed we must continually partake of this Living Water (Ep 5:18). The same life-force flows in and through our veins. So we are partakers of the divine nature together (2 Pet 1:4). Therefore our hearts confirm the working of the Spirit in the hearts and lives of fellow believers.
That is why it should not be easy for genuine believers to be deceived. If we share the same anointing, our ministries must resonate. Although our gifts may differ, our spirits must be in harmony. We must be alert to any signs of spiritual discord among us. Because we are members of one charismatic community. Hallelujah!
