Joel R. Beeke said this quote

Jesus calls all sinners to repent. True repentance is not a nebulous response of sorrow; it requires definite actions. Repentance so transforms the mind that it results in a changed life. Repentance does not merely say “I’m sorry” (similar to what we say when we accidentally step on someone’s foot). Rather, true repentance says from the heart, “I’ve been wrong and grieve over my sin, but now I see the truth, and I will change my ways accordingly.
