But can you help me how to clarify to them the difference between  repenting by giving up their evil lifestyle like pole dancing and  not being saved by “works”, since to stop pole dancing looks like good “works”  having a righteousness that is not our own, but that of Jesus Christ.
That’s a good question, Mildred! Some people have been confused about that and thought that insisting on repentance is insisting on a “work” for salvation.
I would say that the many passages that insist on repentance show that it is required for salvation and not optional (Matt 4:17; 9:13; Luke 13:3, 5; Acts 2:38; 5:31; 17:30).
But repentance and faith sometimes appear together in Scripture; thus I would call them two sides of the same coin. Genuine faith is a repenting faith, and genuine repentance is a believing repentance.
For example, Jesus’ first sermon, in Mark 1:15, was "The time is fulfilled, and the kingdom of God is at hand; repent and believe in the gospel.” And in Acts 20:21, Paul summarizes what he taught everyone as a message “of repentance toward God and of faith in our Lord Jesus Christ.”
I like to illustrate it like this: You can’t turn toward God without turning away from sin, since they are opposites. To turn to God necessarily involves turning from sin. If you are facing east and you want to face west, you must turn from facing east - you can’t look both east and west at the same time!
can you please suggest what are the specific things to believe or trust in order for her to be saved? I have an idea that it’s only to trust Christ’s cross, forgiveness and righteousness, but are there still more in what a person is going to trust in order to be saved kuya?
You are right about trusting in Christ. The message of the gospel is to turn from sin in faith to Christ, trusting him alone for forgiveness. But before someone can do that, they must know that Christ died and rose again - the gospel includes that historical fact. Of course, saving faith isn’t just acknowledging Christ’s death and resurrection; it is trusting him personally and completely. The message is simple: “Believe in the Lord Jesus, and you will be saved” (Acts 16:31).
