The effect of their salvation is seen as forgiveness, reconciliation and healing, bring them into fellowship with fellow believers. It was in this fellowship that the genuineness of their conversions were tested to maximum proportions. The first picture of fellowship is very positive. The second picture of fellowship is equally negative. Just as our heart reflects the real person, so the quality of Christian fellowship reflects the quality of the church.
Some fellowships are superficial while others are artificial.
Some fellowships are based upon quantity, while others are based on quality. It is here in these verses that we catch a glimpse of real fellowship. We see the fellowship of the saints at its best and at its worst. We see an attempt to replace quality fellowship with the superficial and artificial. The real test of Christian fellowship is when people give of themselves.
