Rom.12.9Let love be genuine. Abhor what is evil; hold fast to what is good.
1Cor.11.19for there must be factions among you in order that those who are genuine among you may be recognized.
2Cor.6.6by purity, knowledge, patience, kindness, the Holy Spirit, genuine love;
2Cor.8.8I say this not as a command, but to prove by the earnestness of others that your love also is genuine.
