Testimonies are great things about what the Lord has done for us, but no-one will be offended when you talk about what God has done for you. You need to be specific about sin, about Christ's death on the cross, about others' need for a saviour, and about their need to repent and trust in Christ.
Mark DeverFrom the time of Cain until the last believer before Christ's return, we are all fundamentally in the same boat. We suffer the same spiritual afflictions and tendencies.
