'For Us' in the Bible

My little children (believers, dear ones), I am writing you these things so that you will not sin and violate God’s law. And if anyone sins, we have an Advocate [who will intercede for us] with the Father: Jesus Christ the righteous [the upright, the just One, who conforms to the Father’s will in every way—purpose, thought, and action].

By this we know [and have come to understand the depth and essence of His precious] love: that He [willingly] laid down His life for us [because He loved us]. And we ought to lay down our lives for the believers.

and we receive from Him whatever we ask because we [carefully and consistently] keep His commandments and do the things that are pleasing in His sight [habitually seeking to follow His plan for us].

We have come to know [by personal observation and experience], and have believed [with deep, consistent faith] the love which God has for us. God is love, and the one who abides in love abides in God, and God abides continually in him.
