Ephesians 1:4 contains the most time-disorienting statement about election in the New Testament: "According as he hath chosen us in him before the foundation of the world." The Greek phrase pro katabolēs kosmou — before the overthrow of the world — refers to the period before creation existed. Your being chosen is not a response to anything you did or would do. It precedes the conditions in which doing was even possible. This is the only kind of choosing that cannot be threatened by your worst days.
John 15:16 shifts from the eternal to the personal: "Ye have not chosen me, but I have chosen you, and ordained you, that ye should go and bring forth fruit." Jesus addresses the disciples' own sense of initiative directly — whatever they felt like they were doing in following him, the initiating choice was his. The word "ordained" is tithēmi — to place, to appoint, to set in position. You were appointed before you applied.
First John 4:19 draws the same direction for love: "We love him, because he first loved us." The word "first" is prōtos — first in order, primary, prior. The love you are capable of expressing toward God is a response to a love that preceded yours by an infinite margin. You did not generate love for God and then find that God reciprocated. You encountered a love already directed at you, and your love is the echo of it. Every response you make toward God is downstream of something that was already flowing toward you.
