Fishing was the family business. To follow Him, means to leave the old life behind. It's repentance. It's a blessing that God gives us to multiply in our lives, the things we said goodbye to, when we turned away from everything to follow Him. The old sin nature won't leave you alone. The devil will tap on your shoulder to get you to turn back. When we experience these times, we need to respond with humility. This will lead to turning back to God. God's grace is always enough and there's always more. To start walking with the Lord, you will start having fellowship with others who are walking with the Lord as well. As God is working in us, we will be closer in Him, closer in our walk with Him, and closer in our walk with each other.
