We Can Be Sure

"Here's how we can be sure that we've truly come to know God: if we keep his commands. If someone claims, 'I have come to know God by experience,' yet doesn't keep God's commands, he is a phony and the truth finds no place in him. But the love of God will be perfected within the one who obeys God's Word. We can be sure that we've truly come to live in intimacy with God, not just by saying, 'I am intimate with God,' but by walking in the footsteps of Jesus."
1 John 2:3-6
