The primary Christian virtue is love. If we have all things, but lack love we have nothing.
Truth always must be expressed with love. Truth may be uncomfortable, but the expression of truth should always aim to edify others.
Speaking the truth without love can be worse than remaining silent. We need to pray to find ways to speak truth in love when we cannot find positive ways to express truth.
In all thing we should seek to build other up for the glory of God.
