What does the Bible say about receiving weak believers?

In Romans 14, Paul instructs the church to receive those who are weak in faith, emphasizing that we should not judge or condemn them for their level of understanding. He points out that the kingdom of God is not about external matters such as food or drink, but about righteousness, peace, and joy in the Holy Spirit. This reflects the understanding that all believers are under the Lord and should focus on His glory rather than their own practices. It reminds us that Christ's love and acceptance extend to all His children, regardless of their perceived weaknesses in faith.
