Presbyterians say “Our Father...” during services.

Its not what you say, but what you do that counts.
YHVH is not Don Trump’s Father.
Trump left him in the dust when he called him a liar (”I don’t sin”)
People that think they don’t sin are of their father, the inventor of sin.
That is what the word says.

"But when ye pray, use not vain repetitions, as the heathen do: for they think that they shall be heard for their much speaking."
If you are just repeating a prayer because it is part of the service, you might as well be quoting Dr. Suess for all the good it does spiritually. Repentance has to come from the heart - it requires an acknowledgment of your sin and a genuine remorse and determination to turn from that sin, along with asking for forgiveness.
