Shared ground
These verses close out 1 John’s main aims: the writer addresses people who already believe “in the name of the Son of God,” and he says his writing is meant to produce knowledge—settled certainty—that they have eternal life (v.13). The text presents assurance as something grounded in what has been written about the Son (vv.11–12 just before this) rather than in a vague feeling.
The passage then links that assurance to “boldness” toward God in prayer (v.14). This boldness is real access, but not a blank check: asking is framed by a condition—“according to his will.” Under that condition, God “listens/hears.” The writer then draws a conclusion: if believers know God hears, they can also know they “have” the petitions asked (v.15). The argument is step-by-step: confidence → asking → God’s hearing → confident possession of what is asked.
Where interpretation differs (only where needed)
What “these things” refers to (v.13). Some take it as the whole letter; others take it as the immediately preceding section. Either way, v.13 functions as a purpose statement aimed at strengthening certainty about eternal life for those already believing.
What it means to “have” the petitions (v.15). Some read this as the requests being granted immediately. Others read it as assurance that God has secured the answer, even if its timing or form is not yet visible. Both readings try to honor the text’s strong confidence language while also accounting for the stated condition (“according to his will”).
Why the disagreement exists
The wording in v.15 is very strong (“we know… we have the petitions”), but the passage does not spell out when the petition becomes visible or how God’s will shapes the outcome. Also, v.13’s “these things” is naturally ambiguous: it can point backward to a portion or summarize the whole message.
What this passage clearly contributes
Explicitly, the passage teaches that the writer’s goal is assurance of eternal life for those who believe in the Son’s name (v.13), and that believers have a kind of boldness in approaching God (v.14). It also explicitly states a condition for confident prayer: requests aligned with God’s will are heard (v.14), and God’s hearing is presented as the basis for knowing the petitions are truly secured (v.15). Theologically inferred (but consistent with the logic) is that Christian confidence in prayer is not mainly confidence in personal power, but confidence in God’s attentive response to will-aligned asking (vv.14–15).
