If you know God, it doesn't mean that you will not be tried and tested. It doesn't mean that you will not face problems and difficulties. It does mean that you will have assurance that God is with you, and He is for you.
If you know God, it means He is working in you with love, joy, and peace. Happiness is knowing God loves you. Happiness is the joy of God's presence. Happiness is peace with God. You can say to God, "In Your presence is fullness of joy" (Psalm 16:11).
If you know God, it doesn't mean you will never fail Him and go astray. When you do, God has mercy to forgive you, as you confess your sins. Knowing God's mercy means your sins are forgiven. "Blessed is he whose transgression is forgiven, whose sin is covered" (Psalm 32:1).
If you know God, it is knowing His help with all your needs. At God's throne of grace, there is always help for you. If you know God, you know Him as your Helper. You can confidently say, "The LORD is my helper" (Hebrews 13:6).
