Find a good church
You weren't made to follow Jesus alone.
Christ loves His church, and He puts His people in local churches to grow together. That's where you'll hear His Word preached week by week, share the Lord's Supper, and find people who know you well enough to pray for you, encourage you, and lovingly correct you when you drift. Books, sermons and counselling can help you, but none of them can take the place of a faithful church family.
If you're looking for a church in Southern Africa, the Sola 5 network lists churches that hold to the gospel of grace and preach the Bible faithfully. My own church, Living Hope Church in Hatfield, Pretoria, is one of them. If you're nearby, come and visit us.
