Galatians 5:1 Brothers, if anyone is caught in any transgression, you who are spiritual should restore him in a spirit of gentleness. Keep watch on yourself, lest you too be tempted.
Romans 14:1 As for the one who is weak in faith, welcome him, but not to quarrel over opinions.
Romans 8:6 For to set the mind on the flesh is death, but to set the mind on the Spirit is life and peace.
Romans 15:1 We who are strong have an obligation to bear with the failings of the weak, and not to please ourselves.
1 Corinthians 3:1 But I, brothers, could not address you as spiritual people, but as people of the flesh, as infants in Christ.
Ezekiel 34:16 I will seek the lost, and I will bring back the strayed, and I will bind up the injured, and I will strengthen the weak, and the fat and the strong I will destroy. I will feed them in justice.
James 5:19-20 My brothers, if anyone among you wanders from the truth and someone brings him back, let him know that whoever brings back a sinner from his wandering will save his soul from death and will cover a multitude of sins.
Jude 1:22-23 And have mercy on those who doubt; save others by snatching them out of the fire; to others show mercy with fear, hating even the garment stained by the flesh.
Paul’s wording here speaks not of a determined and hardened sinner. Instead, the idea is of someone who has fallen into sin, finding themselves trapped in a place they never thought they would be. Overtaken “Contains the idea of falling. It is not the deliberate, the planned, aspect of sin that is stressed here, but rather the unwitting element. Mistake rather than misdeed is the force of the word, though without absolution of responsibility.” (Ridderbos)
When a person is overtaken through the weakness of the flesh, the seduction of the worldly, or temptations of Satan, the outcome is a time in a person’s life where the quiet whispers of the Holy Spirit are being hushed and Jesus Christ is not being honored or glorified. Restore them. This job of restoration is often neglected in the church. We have a tendency to either pretend the sin never happened, or we tend to react too harshly towards the one who has sinned. The balance between these two extremes can only be negotiated by the spiritual. It should be normal to do what God says here, but it isn’t. It is all too easy to respond to someone’s sin with gossip, harsh judgment, or undiscerning approval. (Guzik)
“Let the ministers of the Gospel learn from Paul how to deal with those who have sinned. ‘Brethren,’ he says, ‘if any man is overtaken with a fault, do not aggravate his grief, do not scold him, do not condemn him, but lift him up and gently restore his faith.” (Luther)
Let the one who is taught the word share all good things with the one who teaches. Do not be deceived: God is not mocked, for whatever one sows, that will he also reap. For the one who sows to his own flesh will from the flesh reap corruption, but the one who sows to the Spirit will from the Spirit reap eternal life. And let us not grow weary of doing good, for in due season we will reap, if we do not give up. So then, as we have the opportunity, let us do good to everyone, and especially to those who are of the household of faith.
We are not to turn a blind eye to a wandering brother. We are not to neglect a brother fallen to temptations of the flesh. We should recognize it but not embrace it. We should, with love, patience, gentleness, and kindness walk alongside them and through the Holy Spirit’s leading, guide them away from their wandering. How many times have you heard parents tell you about how their teenage child has seeming rejected all of what they had taught them? They do not abandon their child, they still love them, they are patient with them, and they pray for them. Parents who have gone through this will tell you more often than not that their adult child later came to them and apologized for how they acted. Very similar to the parable about the prodigal son.
Where there is spiritual weakness, knowledge, understanding, and true brotherly fellowship in the things of God, in the body of the church, more than likely the ability to recognize yet alone guide that person back. Neglect and complacency in God’s Word will hinder your walk with Him and will always put you on paths that do not honor or glorify Jesus Christ.
