Matthew Henry Commentary 1 John 2:12-14

"I write unto you, [my] little children, because your sins are forgiven you for his name`s sake. I write unto you, fathers, because ye know him who is from the beginning. I write unto you, young men, because ye have overcome the evil one. I have written unto you, little children, because ye know the Father. I have written unto you, fathers, because ye know him who is from the beginning. I have written unto you, young men, because ye are strong, and the word of God abideth in you, and ye have overcome the evil one." — 1 John 2:12-14 (ASV)

As Christians have their distinct conditions, so they have specific duties; but there are commands and obedience required of all, particularly mutual love and contempt of the world. The youngest sincere disciple is pardoned: the communion of saints is accompanied by the forgiveness of sins. Those who have been in Christ's school the longest need further advice and instruction.

Even fathers must be written to and preached to; none are too old to learn. But this is especially true for young men in Christ Jesus, even though they have attained spiritual strength and sound judgment, and have successfully resisted initial trials and temptations, breaking off bad habits and associations, and entered in at the strait gate of true conversion. The different categories of Christians are again addressed.

Children in Christ know that God is their Father; this is wisdom. Those mature believers, who know Him who was from the beginning, before this world was made, may well be led by this knowledge to give up this world. It will be the glory of young people to be strong in Christ and in His grace.

By the word of God they overcome the wicked one.
