This chapter picks up where the previous one picks up: in the tension of being a sinful but also redeemed. Here it reminds us that we should not sin but that we also have Jesus to rely on. It reminds me a bit of when Peter writes about how God provided everything but invites us to have a role. We often try too hard to rely on our own strength to reach purity, but the fact is we can only have it because God redeemed us through his son Jesus Christ. Our human efforts do nothing; it’s only through the cross and the good work Jesus is doing in us that we can achieve anything.
Verses 3 to 6 expand on us further. We are to keep Jesus’ commands out of love for him. Therefore, it’s so important to daily focus on him and what he did for us to motivate us. In times of trouble or temptation we look not to ourselves or our own strength but we look to the cross. Then we can love the Lord our God with all our heart, soul, mind and strength.
The next part of John looks at another way the love for our Lord is express: our love for others. It’s not coincidence that Jesus responded to the question about the greatest commandment with a twofold answer. We are to love our God, which is expressed here in how we love others. These verses also remind us of how Jesus said in Matthew 5. You can’t offer worship if you know a brother has something against you. Jesus came to redeem us with God and each other. Therefore, if there are relational issues within the church, we aren’t living in the fullness of Christ’s redemption.
Verses 12-14 are interesting, exciting and encouraging. The fact that we are told that we have overcome the evil one is an interesting concept in the fight against sin. As we battle against evil desires, we must remember: the victory is won! That’s another good reason to look toward the cross.
The last sections talk about not loving the world because it is temporary and to love what God has given you. We are also warned not to deny Christ. We are to remain in him and remain confident in his promises. In that way we can be pure when he comes again.
