One of the most basic rules of any journey is to let someone know where you are going. Whether it be boating, a walk in the bush, or a long-distance trip in the car, you always let someone know where you are going and what time you expect to be back. If it’s a long journey you might check in with that person occasionally, to let them know how you’re going, how you’re progressing. Why? So that if you get into trouble someone else can help you. So that someone else knows your situation and can step in if you need it.
The Christian journey isn’t really any different. Our walk with Christ is our own, but we are not alone as we walk. God in his kindness has given us brothers and sisters – a family in the church – so that we might bear each other’s burdens (Gal 6:1-3), that we might encourage each other and spur each other on to love and good deeds (Heb 10:24-25); and that, if our brothers and sisters get into trouble on their journey, we might gently restore them and by God’s grace, set them back on their journey with Christ (Jude 22-23; 2 Tim 2:25-26; Gal 2:11ff).
So from time to time tell someone how you're going, and keep an eye out your fellow travellers. Don't attempt this journey on your own - it's too long and too important - and we want to do all we can to ensure that we all make it to the finish line.
