Dear friends, now we are children of God, and what we will be has not yet been made known. But we know that when Christ appears, we shall be like him, for we shall see him as he is. (NIV)

Beloved, we are [even here and] now God's children; it is not yet disclosed (made clear) what we shall be [hereafter], but we know that when He comes and is manifested, we shall [as God's children] resemble and be like Him, for we shall see Him just as He [really] is. (AMP)

Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is. (KJV)
