A.T. Robertson Commentary 1 John 5:14

"And this is the boldness which we have toward him, that, if we ask anything according to his will, he heareth us:" — 1 John 5:14 (ASV)

Toward him (προς αυτον). Fellowship with (προς, face to face) Christ. For boldness see 2:28.

That (οτ). Declarative again, as in verse 11.If we ask anything (εαν τ αιτωμεθα). Condition of third class with εαν and present middle (indirect) subjunctive (personal interest as in Jas 4:3, though the point is not to be pressed too far, for see Mt 20:20,22; John 16:24,26).

According to his will (κατα το θελημα αυτου). This is the secret in all prayer, even in the case of Jesus himself. For the phrase see 1 Peter 4:19; Galatians 1:4; Ephesians 1:5,11.

He heareth us (ακουε ημων). Even when God does not give us what we ask, in particular then (Hebrews 5:7f.).
