Pleasing God is not a matter of knowing all the “right” doctrines. Rather, it is a matter of doing His will. Therefore, the goal of being “orthodox” and avoiding all “heresy” is irrelevant to the interests of God. Pursuing orthodoxy and avoiding heresy is a goal which commands the attention of Christians – the churched. They want to be sure that they are all orthodox even though they don’t all agree on what orthodoxy is. This is a mindset actually alien to faith even though orthodox Christians think it constitutes faith.
Faith is trust in God. It is conviction one holds before God – not before his fellow human beings. Faith pleases God even when it doesn’t please the church.
The church calls a heretic anyone who does not espouse her doctrines – even though she has myriad and often conflicting doctrines. God says, “Come to Me all who are weary and heavy laden, and I will give you rest.” You could believe all the wrong things about the Second Coming and still bring pleasure to God’s heart if you are trusting Him and obeying Him with your life today. Conversely, you could know all the right things about the Second Coming and be someone who completely repels Him.
Therefore, don’t worry about knowing all the right facts about God. Focus instead on trusting and obeying – that is, loving – the Lord Jesus Christ. Do this and all the right facts will eventually manifest themselves to you. But even that doesn’t happen until you’ve died and gone to heaven, you still will have had the pleasure of knowing Him and pleasing Him during your time upon earth.
