The tetragrammaton was god's old covenant name only, for his covenant people the Israelites. "He causes to become," as a loose meaning of YHWH , was fulfilled in Christ. God was now the father of all national groups, not just the Israelites. Hence why Jesus never once addressed his heavenly father in prayer as YHWH, instead mostly addressing him as father, and hence why the name was deliberately left out of the NT.
And of course not forgetting that the apostle Paul was the apostle to the nations, not Jews. The Hebrew characters YHWH or some derivation thereof appearing amongst Paul's Greek epistles to all those Greek speaking pagan converts would mean absolutely nothing to them. Ever notice that Paul in his famous speech at the Areopagus (Acts 17) never once refer to the one true God as YHWH?
