God has branded believers as his, putting his mark on us; made it clear that we’re the real deal, and guaranteed our protection in transit to the age to come. The Spirit is God’s maker’s mark on us. It shows us that he is committed to us, and that his promises are reliable. For this to be helpful, it has to be visible to both you and others that you have been sealed.
How do we know we’re in? How do we know that God loves us and will preserve us to the end?
It’s got nothing to do with Bourbon, before you get too excited.
There are three ways that we know that we know him. I’m talking about what we commonly call assurance, the certainty that you are a Christian, you do know Jesus, and that you’re in. That’s what you need when your back is against the wall and you desperately need to know that death is beaten, that sadness will wither, and that Jesus wins. You’ve been taught it, you’ve read it, you declare it, but you just need to know. That’s assurance.
Deductive Assurance
The first way is what I would call ‘deductive’, what we typically call logic. This is when we read in the Bible that if we trust Jesus and follow him then God will not count our sins against us, and instead considers us as though we were his Son. We then think through whether or not we trust Jesus and are trying to follow him—”yes, as best I can, but a long way from perfectly.” Therefore, I must be one of Jesus’ followers and I can trust that God will be true to his word. We know with our heads that it’s true.
Inductive Assurance
The second way I’d call ‘inductive’. This is where we infer things from what we observe. We see progress in our lives since we met Jesus and continue to see that progress. We keep changing for the better in ways that we couldn’t make happen ourselves. Sometimes this requires the long view, but this is proof that what we think is true is true. Therefore, we must be one of Jesus’ followers and God is already being true to his word. We know with our lives that it’s true.
Direct Assurance
The third way I’d call ‘direct’. It’s not based on logic, but on experience. It’s when we meet with God in a powerful way and know—just know—that he loves us, is for us, and counts us as his children. It proves that everything I’ve read that is true in general, and that everything I’ve seen that seems to be true in my life, is specifically, intimately, individually true for me. Therefore, God loves me, so he is true to his word. We know with our hearts that it’s true.
This direct assurance I’ve written on recently: the feeling of joy that proves the ‘knowing’ of hope to be true.
We need all three: the head, the life, the heart. Each one proves the others. The direct heart experience is the one that does the heaviest lifting in hard times. It’s the one that is most fitted to carrying us through life, but it needs the other two to authenticate it.
If you’re missing deductive assurance, then go back to the Bible, ask Jesus, do you really believe this stuff? If you’re missing inductive assurance, then go to Jesus in prayer—ask him to show you how your character is developing and your faithfulness increasing. Ask your church family too, our friends often see us clearer than we see ourselves.
