"Truth is Christ" (Brandon Peterson) and my biblical concerns!

Are there any biblical concerns to state that salvation, or deliverance, from hell to heaven is by “repent + call + believe” as stated, or implied, on many occasions on the “Truth is Christ” YT Channel?
What about the globe model of the Earth?
How about a borderline obsession with biblical numerics?
“And saying, The time is fulfilled, and the kingdom of God is at hand: repent ye, and believe the gospel.” (Mark 1:15)
“But they have not all obeyed the gospel. For Esaias saith, Lord, who hath believed our report? (Romans 10:16)
“Who hath believed our report? and to whom is the arm of the LORD revealed?” (Isaiah 53:1)
