JMNT(i)
7 Beloved ones, we are (or: can and should be) continuously loving one another, because love (or: the urge toward reunion and acceptance) exists continuously (or: is) from out of the midst of God, and every one continuously loving has been born, and exists being a born-one, from out of the midst of God, and constantly experiences intimate knowledge of God (or: comes to know by experiences from God; gains knowledge and insight by the experience which is God).
8 The one not habitually loving has not come to know God by intimate experience, because God continuously exists being Love (or: for God is Love and Acceptance).
9 Within this, God's Love is instantly manifested (or: was at one point made visible; is made apparent and clear) within us (or: among us), in that (or: because) God has sent (dispatched) His uniquely-born (or: only-begotten) Son as a Representative (Envoy; Emissary) into the ordered System (world of society, culture, religion and government; or: the cosmos; or: = the aggregate of humanity), to the end that we would live (or: can experience life) through Him.
10 Within this exists (or: is) the Love, not that we ourselves have loved [other MSS: not that we ourselves love or accept] God, but in contrast, that He Himself loves us and sends (or: urged toward reunion with us and sent) His Son as a Representative (Emissary): a cleansing, sheltering covering around our sins (failures to hit the target, errors, mistakes, deviations).
11 Beloved ones, since thus (or: in that manner) God loves (or: loved) us, we also are constantly indebted (or: under obligation) to habitually love and accept one another.
12 No one (or: Not even one) has yet once (or: ever yet) gazed upon God as an object in a theater (as a public spectacle). If we are (or: may be) habitually loving (urging toward reunion, acceptance and participation in) one another, God constantly remains (dwells, abides) within us, and His love (or: the love, which is Him,) is existing having been brought to its goal and is now matured, perfected and has reached its destiny within us, and among us.
13 Within this we are continually knowing by experience that we are constantly remaining (dwelling; abiding) within the midst of, and in union with, Him and He Himself within us, because He has given to us from out of His Breath-effect (or: Spirit; Attitude).
14 And we have gazed upon this public situation, and are repeatedly testifying (giving witness and evidence) that the Father has sent forth (dispatched as a Representative) the Son – [the] Savior of the world (or: Deliverer of the ordered and controlling System of religion and secular society; Restorer of the universe; or: = the Rescuer and Healer of all humanity).
15 Whoever may speak in accord (confess; avow; say like words; say the same thing; agree) that Jesus exists being God's Son (or: is continuously the Son which is God), God continuously dwells (abides), remaining in him, and he himself within God.
16 And we have come by intimate experience to know and have believed, trusted and are convinced of the Love which God has (or: holds) continuously within (or: among) us. God exists continually being Love (God is Love), and the person continuously remaining (dwelling; abiding) within, and in union with, the Love, is continuously remaining (dwelling; abiding) within, and in union with, God – and God constantly dwells (remains; abides) within him and in union with him.
17 Within this the Love has been brought to its goal, been matured, reached its destiny and is now perfected with us, to the end that we may continuously have confident freedom of speech (the boldness of a citizen to speak publicly without fear of punishment) within the day of sifting and separation (distinction, evaluation and decision; judging; judicial proceeding; or: administering of justice), because just as That One is, we also continuously exist being: within the midst of this ordered System (or: because in this world of culture, religion, economy and government, even we, ourselves, progressively exist – correspondingly as, and to the according level as, That One continuously exists and is progressively being).
18 Fear does not exist within the Love, but rather perfect love (mature love; love having reached its goal) repeatedly (habitually; progressively) throws the fear outside, because the fear constantly has and holds a pruning (a curtailment; a checking; restraint; a lopping off – thus, a correction). But the one habitually fearing or dreading has not been perfected within the Love (has not been brought to the destined goal of maturity – in union with love).
