I have fallen into a grievous sin the last few years and I am afraid that I am falling away from the faith. I have been saved and still believe the gospel with all my heart. However, my sin has beaten me down to the point that I have become indifferent to things of God (i.e. don’t want to go to church, don’t want to read my bible, etc.) and I have no fire or zeal anymore for the gospel. I believe it but I have no power to live it. It’s like I have given up.
Since the Holy Spirit was sealed within us at the moment of belief as a deposit guaranteeing our inheritance, falling away from the faith is something that can only happen to those who never truly believed in the first place.
When we experience a time of separation, it’s good to remember that God is constant (Hebrews 13:8) so it always means something is different with us. It sounds like for you that something is unconfessed sin. Satan is using the guilt you’re harboring to drive a wedge between you and God. He can’t have you, but he can use your guilt to make your life miserable to the point where you begin to doubt your salvation.
Use these remedies for your situation. First, confess this sin you have fallen into. The Bible says, “If we confess our sins God is just and faithful and will forgive our sins and purify us from all unrighteousness” (1 John 1:9). Then apply James 4:7-8. “Submit yourself to God. Resist the devil and he will flee from you. Come near to God and He will come near to you.” God didn’t move away from you, you moved away from God. When you come back to Him He will come back to you. Pray, read your Bible, remain in the company of believers, and strive to maintain a positive attitude.
Paul said, “Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus.
Finally, brothers and sisters, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable–if anything is excellent or praiseworthy–think about such things. (Phil. 4:6-8)
