Everywhere you look there is temptation. Turn on the radio. Turn on the tv. Walk down the street. Go to Facebook. Temptation is all around us. As followers of Christ, Paul reminds us to be on guard at all times, to stand firm, to be courageous, and to be strong.
To be on guard means to be awake. It carries with it the idea of not sleeping on the job. In order to live the type of lives Christ has called us to, we need to be aware of what is going on around us. We need to open our eyes and see the dangers ahead and then do what we can to avoid them. Another way to say this is don’t be a sleepwalker wandering aimlessly about with no real purpose or conviction.
To stand firm means to hold one’s ground. Specifically, Paul is saying to hold one’s ground when it comes to the faith, that is, the gospel message. Don’t be swayed by popular opinion or the latest fads – the gospel is truth and it is absolute. The message that Jesus died on the cross for your sins, rose again to conquer death, and now invites each of us into a relationship with him cannot be changed by anyone. Don’t let others distract or burden you with “gospel +” – that is, people adding to the gospel message or on the other side, people subtracting from it.
Be courageous means having the characteristics of an adult as opposed to a child. Be mature in your faith and don’t allow little things to distract you from the message of faith and hope. Don’t be lured into fear when you already know the truth.
Be strong means to become strong beyond the average. You are not average! You are a child of the King! In him you can find strength to conquer whatever battles you face, whether they be outside temptations or the inner temptations, including the temptation to worry.
As a child of God you are stronger than you know, you are more courageous than you can imagine, and you can stand firm in your faith – all by the power of the Holy Spirit living within you.
