The apostle John’s longing has been that those who have believed in Jesus would KNOW that they have eternal life through faith in Jesus (1 John 5:13).
Now he goes on to write of three additional things that Christ Followers know also;
1.We know that we are from God.
So many personal problems begin when this truth is not firmly grasped and held on to by the believer in Jesus. The devil repeatedly tries to undermine the truth that we have been adopted as God’s beloved children through faith in Jesus (see John 1:12, 1 John 3:1).
Assurance, security, peace, acceptance, love, protection, hope for answered prayer…are all rooted in this truth. God being our Father changes everything – it’s a classic case of; ‘it’s not what you know but who you know’! Even better it’s not about who you are but who’s you are!
If you are battling with feelings of fear, anxiety, rejection, or loneliness or feeling under-valued or over-looked or unseen, you need to tap into this truth, again and again, the sons and daughters of God most high need never struggle with questions of this nature.
If God the Father loved you enough to send Jesus to the cross to die in your place for your sin while you were still His enemy, then having already done that, how much more will He not also along with Jesus give you all things? (Romans 8:32). Know these things.
2.the whole world lies in the power of the evil one.
Know also, however, that in this present age post-Christ’s resurrection but before His return the world around us is under the control and influence of the evil one – the devil.
Although the devil has been triumphed over by Jesus on the cross (Colossians 2:14-15), although his days are numbered, and his final destiny is the final judgement of God in the lake of fire (Revelation 19:20) – he still has power in this present age. And so the world is full of traps and temptations as the devil tries to derail people from faith, worship and trust in God.
Knowing that you have an ultimately defeated, but real enemy who prowls around like a roaring lion looking for someone to devour (1 Peter 5:8) will help you to be sober-minded and alert. Remember that ‘He who is in you is greater than he who is in the world’ (1 John 4:4) – so do not live in fear but be alert to his cunning schemes and traps.
3. And know that Jesus is the one true God (vs20)
The knowledge that we have a real enemy is sandwiched between knowing we are God the Father’s beloved children (vs19) and that we have believed in Jesus Christ the one true God and we ‘know him’ and so we can know we have eternal life with Him.
Don’t give in to doubts and lies from the enemy about who Jesus is – what you have believed is true, and you will be richly rewarded into eternity for holding on to that truth. There is no god besides our God, Jesus Christ!
Armed with the knowledge of these three things, John concludes with something we ought to DO.
Little children, keep yourselves from idols. (vs21)
Don’t give your trust, your worship or devotion to anything or anyone other than Jesus Christ. But what is an idol? Is it just a statue of sorts?
An idol is anything that we seek to get significance, meaning, identity, belonging, purpose, security, peace or happiness from – someone or something that occupies the place of God in our lives. Mark Dever said; “Idolatry is sin in its purest form: it is trusting something other than God.”
The apostle closes his letter with a warm warning – keep yourselves from idolatry. Worship, serve and love God only!
