So you're feeling bad. You wonder about God's love. There are two avenues of approach. You can throw in the towel, give up on the idea of assurance, and swim in a pool of self-pity.
Or you can take some action. "Why are you in despair, O my soul? And why are you disturbed within me? Hope in God, for I shall again praise Him, the help of my countenance and my God" (Psalm 42:11 and 43:5).
There is a biblical principle at work here. The apostle Paul talks about it. "The things you have learned and received and heard and seen in me, practice these things, and the God of peace will be with you" (Philippians 4:9). To experience peace of heart, we must therefore practice biblical principles.
Here is an example. "Let us consider how to stimulate one another to love and good deeds, not forsaking our own assembling together" (Hebrews 10:24-25). When we worship together, God meets with us. "Draw near to God and He will draw near to you" (James 4:8).When we study together, God confirms we are His.Paul says to the church, "We are the temple of the living God; just as God said, 'I will dwell in them and walk among them; and I will be their God, and they shall be My people'" (2 Corinthians 6:16).
