1 John 2:5

5But if anyone obeys his word, love for God is truly made complete in them. This is how we know we are in him:

5but whoever follows His word, in him the love of God has truly been perfected. By this we know that we are in Him:

5But whoever habitually keeps His word and obeys His precepts [and treasures His message in its entirety], in him the love of God has truly been perfected [it is completed and has reached maturity]. By this we know [for certain] that we are in Him:

5But if anyone keeps His word, the love of God has been truly perfected in him. By this we know that we are in Him:

5but whoso keepeth his word, in him verily hath the love of God been perfected. Hereby we know that we are in him:

5But hee that keepeth his worde, in him is the loue of God perfect in deede: hereby wee knowe that ye are in him.

5But God’s love has most certainly been perfected in whoever keeps his word. This is how we know that we are in him:

5But if anyone obeys God’s word, then that person truly loves God. Here is how we know we belong to him.

5But anyone who obeys God's message shows that he really loves God completely. So this is how we know that we belong to God.

5and whoever may keep His word, truly the love of God has been perfected in him; in this we know that we are in Him.
