The lesson is -- trust your experience with Gods word, let them be a lamp unto your feet and a light to direct your path, whatever people may have to say against it. If you have found that Jesus Christ can help you, and has loved you, and that your sins have been forgiven, because you have trusted in Him, do not let anybody laugh or talk you out of that conviction.
Jeremiah 9:23-24 says thus says the Lord, let not the one who is wise and skillful boast in his insight; let not the one who is mighty and powerful boast in his strength; let not the one who is rich boast in his (temporal satisfactions and earthly ) abundance; but let the one who boasts boast in this, that he understands and knows me 9and acknowledges me and honours me as God and recognizes without any doubt) that I am the LORD who practices lovingkindness, justice and righteousness on the earth, for in these things I delight, says the LORD
