The words 'what kind' in the Greek indicate an otherworldly or supernatural love. It is a kind of love that the Holy Trinity has for His children but one that we do not understand fully...because it comes from another place than from men, or on earth. It's astounding to think of this love! It is so deep and so perfect. It's abstract because it comes from the fountain of the Father's heart but it is real because He demonstrates it-
but God shows his love for us in that while we were still sinners, Christ died for us. (Romans 5:8)
Warren Wiersbe explains that in the 1 John 3:1 verse and onward, John gives us three reasons for a holy life.
God the Father Loves Us (1 John 3:1–3)
God’s love for us is unique. First John 3:1 may be translated, “Behold, what peculiar, out-of-this-world kind of love the Father has bestowed on us.” While we were His enemies God loved us and sent His Son to die for us!(Source: Wiersbe, W. W. (1996). The Bible exposition commentary (Vol. 2, p. 504). Wheaton, IL: Victor Books.)
The whole wonderful plan of salvation begins with the love of God.
Many translators add a phrase to 1 John 3:1: “That we should be called the sons of God, and we are.” “Sons of God” is not simply a high-sounding name that we bear; it is a reality! We are God’s children! We do not expect the world to understand this thrilling relationship, because it does not even understand God. Only a person who knows God through Christ can fully appreciate what it means to be called a child of God.
First John 3:1 tells us what we are and 1 John 3:2 tells us what we shall be. The reference here, of course, is to the time of Christ’s coming for His church. This was mentioned in 1 John 2:28 as an incentive for holy living, and now it is repeated.
God’s love for us does not stop with the new birth. It continues throughout our lives and takes us right up to the return of Jesus Christ! When our Lord appears, all true believers will see Him and will become like Him (Phil. 3:20–21). This means, of course, that they will have new, glorified bodies, suited to heaven.
But the apostle does not stop here! He has told us what we are and what we shall be. Now, in 1 John 3:3, he tells us what we should be. In view of the return of Jesus Christ, we should keep our lives clean.
All this is to remind us of the Father’s love. Because the Father loved us and sent His Son to die for us, we are children of God. Because God loves us, He wants us to live with Him one day. Salvation, from start to finish, is an expression of the love of God. We are saved by the grace of God (Eph. 2:8–9; Titus 2:11–15), but the provision for our salvation was originated in the love of God. And since we have experienced the love of the Father, we have no desire to live in sin.
This heavenly love is given to us that we are children of God. This God, this holy and loving and just and perfect Father, revealed Himself to us in His word. His word is where we learn more about Him, His love, His plan for us.
His word is edifying and instructive and all sufficient. (2 Timothy 3:16). It pierces, transforms, convicts. I read Dr Albert Mohler's comment yesterday when he put up this link to Dr John Piper's video regarding the importance of reading the Bible:

My heart was really moved by this new video from @JohnPiper -- "God Wrote a Book." Please see it and share it. http://ow.ly/O366HI did view it and I did share it. I encourage you to watch, it is 5 minutes.
The love the Father has for us brings peace and gratitude. It is a refreshing and wonderful feeling, knowing by His grace I am a child of God. What further joys await when I am lifted to His holy habitation to see Him as He is. That is where the 1 John 3 verse goes, it says in vv. 2-3,
Beloved, we are God’s children now, and what we will be has not yet appeared; but we know that when he appears we shall be like him, because we shall see him as he is. 3And everyone who thus hopes in him purifies himself as he is pure.
Pure. Brothers and Sisters, we will see Him as He is. Read John 17 if you want to fall on your face in gratitude in being a recipient of this great love the Father and the Son have for each other and which Jesus opened that circle to include us within it. We are secure in the bosom of the holy and loving Trinity, and someday, we shall see Him as He is.
