Verses 2-3: Beloved, now we are children of God, and it has not appeared as yet what we will be. We know that when He [it] appears, we will be like Him, because we will see Him just as He is. And everyone who has this hope fixed on Him purifies himself, just as He is pure.”
Continuing from verse 1, John emphasizes our present position: that we are children of God, His spiritual offspring. But it has not yet appeared what we will be. The Greek word for appeared means to be made visible or manifest, W.E. Vine clarifies this:
The Scriptural sense of the word, is more than to “appear.” A person may “appear” in a false guise or without a disclosure of what he truly is; to be manifested is to be revealed in one’s true character.1
The Apostle Paul describes this true character as the “new self2 who is being renewed to a true knowledge of the One who created him” (Colossians 3:10). When John states what we will be, he is suggesting that our new self will become “something inconceivably glorious”3 in the future, when our time is finished here on earth. It will entail not only our spiritual transformation (Romans 12:2) but also our physical change into an immortal body (1 Corinthians 15:53ff).
But now a problem arises in the interpretation of this verse. The reason being that the next phrase could be translated from the Greek in two ways: “when He appears” or “when it appears.” The latter seems to be the logical choice, referring back to “it has not appeared,” with reference to our true character.4 So that when our true character (it) has been made manifest (appears), we have the assurance of knowing that “we will be like Him.” The question is: in what way will we be like Him? One thing for certain, we will not be like Him in His deity. Therefore, we must recognize that what John is referring to is our future spiritual and physical composition.
John elaborates upon this, stating in effect, that without a doubt “we will see Him just as He is.” This is an absolute truth statement. Which means we will need to take John’s word on this, for he saw Our Lord during His early 30’s on various occasions while He was on the earth: in the flesh (John 1:14); at the Transfiguration event (Luke 9:28-36); in His resurrection body (John 21). Thus, we will see Our Lord just as He appeared when John last laid eyes on Him ascending into Heaven (Acts 1:9-11). Our Lord provided proof of His resurrected body when He dispelled Thomas’ skepticism (John 20:19ff) and descriptive details of the nature of His present resurrected body, that it is physical and not spiritual:
“See My hands and My feet, that it is I Myself; touch Me and see, for a spirit does not have flesh and bones as you see that I have.” (Luke 24:39)
By this verse, John is claiming that we have a future beyond the initial stage of being a child of God: spiritually, when we achieve maturity in the knowledge of the truth (1 John 2:21; cf. Ephesians 4:13) and physically, upon leaving this present world when we will be like Him in our new resurrected immortal body, just like the Our Lord’s (cf. Romans 8:29; 1 Corinthians 15:49; Philippians 3:21).
This Hope
What is ‘hope’? Most people define it as the dictionary does: “To wish for a particular event that one considers possible,”5 accepting the possibility that what is wished for may not come to pass. But that is not Biblical hope. Biblical hope is best defined as “a looking forward to in confident expectation.”6
Whenever we see this word ‘hope’ in Scripture, we should understand it to mean ‘confident expectation.’ When we consider any of God’s grace provisions—salvation (Romans 8:24; 1 Thessalonians 5:8); eternal life (Titus 1:2; 3:7); our resurrection (Acts 23:6; 24:15); future glory (Romans 5:2)—we can have a confident expectation of the certainty that He will fulfill what He promises. The writer of Hebrews emphasized this aspect of our hope in God’s eternal provisions, that “This hope we have as an anchor of the soul, a hope both sure and steadfast” (Hebrews 6:19). And this is what John is saying here, that we can be confident that we will be like the Lord Jesus Christ when we see Him after our time on earth has ended.
Therefore, John maintains that for every believer this hope should be fixed on Him. The word fixed is an added emphasis of the Greek phrase: upon Him. Wuest asserts that “the idea is, ‘hope resting upon Him,’ or ‘hope set on Him.’”7 The Apostle Paul concludes that we should be “Looking for the blessed hope and the appearing of the glory of our great God and Savior, Christ Jesus” (Titus 2:13).
Purified Believers
John concludes that when believers have this hope fixed upon the knowledge that at a future time “we will be like” Jesus Christ, that the rightfully expected response should be to consistently purify oneself. This requires the believer to know and confess their sins (1 John 1:9) and to develop “the habit of resisting every defiling influence and keeping oneself free from it.”8 To achieve this the Psalmist prescribes: “Depart from evil and do good, So you will abide forever” (Psalm 37:27).
However, how can we accomplish this? We must remember Our Lord stated that “apart from Me you can do nothing” (John 15:5b). So we dare not attempt this in our own strength. We need a power source that will separate us from evil in order to achieve this purity, that power has been made available for us by the sanctifying Word of truth (John 17:17) that we acquire by the Holy Spirit’s teaching (John 14:26; 16:13).
The fact is, we need to be pure in order to be effective in our walk of faith. Jesus Christ doesn’t need to become pure; He proved that He is pure by His holy life, having successfully resisted “every vile and sinful surrounding and temptation.”9 It is the reason why John can decisively state without any ambiguity, that the essence of Our Lord Jesus Christ is that of absolute purity.
Are we striving in our moment-by-moment walk of faith to be pure, just as He is?
