Here are three ways that I recommend to revive a lukewarm faith. Which ones would you suggest?
Witnessing to the Lost
If you want to turn a tepid faith to boiling hot, start witnessing to the lost. What this does is give you a good memory bank of Bible verses because you’re going to need them: verses that talk about the eventual fate of all who refuse to repent and trust in Christ (Rev 20:12-15), why we need the Savior (John 3:18b, 36b), what Christ’s death on the cross can do (2 Cor 5:21), and every one of us having an appointment with death and then the judgment (Heb 9:27). Witnessing to the lost is a scary thing, yes, but it is one of the most rewarding things that a Christian can do. There is such indescribable joy and peace after you have shared the gospel of Jesus Christ, and it forces you to memorize scriptures that show people why they need Christ (Rom 3:10-11, 23; 6:23).
Start a Ministry
A few years ago, I jumped into a nursing home ministry cold feet and started a Bible study. I had no clue what I was doing. I was apprehensive because I didn’t know anyone, nor did anyone know me, but after a few weeks, the residents, their families, and the staff began to look forward to my visits, and I found out that next to witnessing, there is no greater joy than to visit with these seniors, who are very lonely and just want someone to talk to. And guess what? “Religion that God our Father accepts as pure and faultless is this: to look after orphans and widows in their distress” (James 1:27). There are two things worth mentioning here. This is one thing that God the Father accepts as pure and faultless religion. Also, how many in a nursing home are orphans and widows? Almost every one of them! That will fire up your faith, I guarantee it!
Take a Risk for the Kingdom
In many ways, a faith that has never been tested can never be trusted, so if you ever get an idea about doing something radical for the kingdom, do it. I would put it this way: Never suppress an urge to be generous. I heard one pastor who was in a grocery line watching a woman with two children and no wedding ring. This poor woman was counting out her change to see if she had enough to pay for her groceries. It appeared that it was going to be close, so the pastor had an urge, or perhaps a Spirit-induced impulse, to just pay for the woman’s grocery bill. This woman saw what he did, started crying, and thanked him. The pastor never said who he was but only said that “God has been good to me, and He seemed to be telling me to help you, so I did.” Interestingly, a few weeks later the woman happened to show up at his church, and she recognized him. That woman later came to a saving faith in Christ. Being a single mother might be the hardest job on earth, so if you get an urge or impulse to be generous to a single mother, or anyone for that matter, do it–take a risk. God will not forget your generosity.
Do you really want Jesus to feel like He wants to spew you out of His mouth because your faith is so lukewarm that it’s disgusting to Him (Rev 3:16)? Think that’s not serious? The Greek word for spew is “emeō,” which literally means “to vomit” or “throw up.” That’s how sick our lukewarm faith can make Jesus feel–so sick to His stomach that He vomits us out. Gross, I know, but that is the original language it is written in, so fire up your faith, witness to the lost, minister to the lonely, take a risk, and help someone who needs it. You’ll revive that lukewarm faith into a boil.
