To seek the Lord is to obey his commandments. The Bible is clear on this. Almost everywhere when seeking God is mentioned, you will find a mention of or command toward obedience nearby. Deuteronomy 4:29 is no exception.
When we seek God, we are not seeking to please him (what could God possibly gain from us?) Instead, we only seek to be with him, to seek his presence through our obedience which is our connection to the true vine. When we are in line with Christ, we are in Christ as Christ is in the Father. If you seek him, you will find him for he will be in you.
When we obey, we simply follow the path God has already laid out for a healthy and functional body. If the heart decides to act out on it's own, we call it arrhythmia, or in baser language, a serious problem and threat to the overall wellbeing of the body. We never act on our own, but always our smallest actions have large impacts on everyone around us.
So one act of love can completely change someone's life and the life of everyone around them, but so can an act of hatred. Be mindful of your actions and be careful what you multiply. You will reap what you sow.
