That doesn’t say prayer. It says.…whosoever CALLS on the name of the Lord. Show me where that is tied to prayer in the NT. I can show you how it is tied to baptism and obedience to the gospel. But its NOT tied to prayer.Wrong. Romans 10:13 says, "For everyone who calls on the name of the Lord will be saved." He's clearly speaking of a call to God for salvation, i.e., a prayer.
"But the tax collector, standing far off, would not even lift up his eyes to heaven but was beating his breast and saying, 'God, be merciful to me, a sinner!'" (Luke 18:13)
"Immediately the father of the child cried out, 'I believe; help my unbelief!'" (Mark 9:24)
Three times do people call on God/are told to call on God to ask for salvation.
in Lk 18 you have a Jew praying to God in the temple. So what? That was what Jews were supposed to do. 2 chr 7:12-15. are you a Jew? Do you have a temple to go to?
Mk 9 is another Jew (jews were in a covenant relationship with God) and has nothing to do with an alien sinner needing to be saved from their sins. Do you have any examples under the new covenant? Jesus did away with the first so he could establish the second.
