I appreciate this question @SeanO. I’m excited to see other people’s recommendations as well, since it may be able to help me in checking resources which I have not used before in my personal walk as I grew in the Lord. What will be shared here may help us in helping others who want to seriously grow in their faith.
Personally, Jerry Bridges’ books helped me as I was first growing in my theology as a Christian. It’ll help you understand grace properly, which will not lead to legalism and antinomianism. And practically it’ll help you in your sanctification.
Some of his books are: The Pursuit of Holiness, The Practice of Godliness, Respectable Sins, The Discipline of Grace, Transforming Grace, Growing Your Faith, True Community, and Trusting God Even When Life Hurts.
In evangelism, what shaped my practice fundamentally are videos from Ray Comfort. The Way of The Master or Living Waters really has some good videos in practice of their method of how to share the gospel. Meaningful Evangelism by Andy Smith was helpful to me as well. It’s kind of Abdu Murray’s Grand Central Question in apologetics, but in evangelism format. Like you explain the gospel depending on what you think the person values the most. Like if they value family, you explain sin as resulting to a loss of relationship with God, as God being a good Father. That what Christ had done would make sure that everyone who believes would be reconciled to God.
I think this may be general resources which I could share at the moment. I think other things I’ve read may depend on the person’s situation.
