What is it to seek? Seeking is to set the mind and heart on something. We go to Scripture and read it and our brain processes the ideas being communicated and we let our heart and mind be fixed on those realities. You seek Christ by calling upon Him and pleading with Him.
When someone is seeking Christ, one question to ask is what they're seeking Him for. Are they seeking Him to be saved from sin or to just be saved from trouble they find themselves in?
