It’s never too late, and your sins can be forgiven. The people in the church in Corinth had done all sorts of sinful things (1 Cor 6:9) but Paul says “But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God.” (1 Cor 6:10).
There is no age-limit on becoming a Christian. Some people come to the Lord early in life, others very late. I once attended the baptism of a lady in her 90s. She lived only a few years as a Christian, but that won’t matter in God’s kingdom.
Jesus once gave a parable about workers in a vineyard (Matthew 20:1-16). It didn’t matter what time of day the workers began, they were each paid the same at the end of the day. It is like that with the kingdom of God. No matter when we become Christians, the result is the same.
