Thankfully, James’ letter is full of cures for double-mindedness.
First, be sure you are a true believer, a servant of the Lord Jesus Christ (v. 1).
Second, correct any dispersion or separation from Christ’s church (v. 1). Adopt God’s plan for caring for you and all His children: His church to which He has given spiritual gifts—pastors, teachers—His life-sustaining sacraments, and His own presence in worship. View the church as vital to your spiritual welfare and service.
Third, confess double-mindedness regarding God’s plan of sanctification, which purposely utilizes trials in order to build up our faith (vv. 2–4). The double mind sees evil in the trial and God only on the periphery. The spiritually focused mind sees God in control and working for our good. David said, “It is good for me that I was afflicted” (Ps. 119:71). James says, “Count it all joy” (James 1:2). You can do this only if your mind is singularly focused on God’s plan.
Fourth, be single-minded about God’s generosity toward you. Use James 1:5–8 to help you repent of doubting God’s goodness and His generosity. Focus on the “crown of life which He has promised to those who love Him” (v. 12). Relish verses 17–18:
Every good gift and every perfect gift is from above, coming down from the Father of lights with whom there is no variation or shadow due to change. Of his own will he brought us forth by the word of truth, that we should be a kind of firstfruits of his creatures.
Finally, see the bigger picture. See all of James’ exhortations and wisdom in light of the One he called the “Lord,” even Jesus Christ (v. 1).
Jesus was dispersed—sent into this hostile world by the Father’s will. He was separated from the true church in heaven and was immersed in a far more rigorous calling than we will ever face.
Jesus willingly, joyfully faced the trials His Father sent, fulfilling James’ exhortation in verse 2.
Jesus persevered in and grew through His trials (vv. 3–4). Jesus met and defeated the tempter via the Word, much prayer, and faith without doubting (v. 5). He kept His mind singularly focused on pleasing the Father.
Jesus received the crown of life (v. 12) for His complete faith and obedience. He was highly exalted, raised from the dead, received in glory back to heaven. As King of kings, Jesus now rules over all things for us, the church (Eph. 1:20–23). That means that Jesus is in charge of saving us, sanctifying us (through trials), employing us in His service, and delivering us at last spotless into His glory.
Keep your mind focused on Jesus, and your heart will be aflame.
