In the text

For he is God’s servant for your good. But if you do wrong, be afraid, for he does not carry the sword in vain. He is God’s servant, an agent of retribution to the wrongdoer.
1 Corinthians 15:2εἰκῇ
By this gospel you are saved, if you hold firmly to the word I preached to you. Otherwise, you have believed in vain.
Galatians 3:4εἰκῇ
Have you suffered so much for nothing, if it really was for nothing?
Colossians 2:18εἰκῇ
Do not let anyone who delights in false humility and the worship of angels disqualify you with speculation about what he has seen. Such a person is puffed up without basis by his unspiritual mind.
