Matthew 6:33 says, "But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you."
You cannot really seek God's kingdom--that is, God's way of doing things--the way God would have you to until you are born again. Jesus let Nicodemus know in John 3:3 that we cannot even "see" the kingdom unless we have been born again. When someone is born on earth, they are born into a certain natural citizenship. If you're born in America for example, then you are considered an American. You have American citizenship. So what does it really mean to be born again? It means you are born again spiritually, and you're citizenship is of the Kingdom of God. He is your King and you are one His subjects. He is a loving King and always has your best interests at heart. He rules from within our hearts to work His Kingdom business in the earth. When we seek God's kingdom, what is so great is that we don't have to worry about the things we need. God supplies all our needs. The Gentiles eagerly seek after things, but when we seek God, we get all that God wants us to have. So we don't even have to stress! So not only do we gain new citizenship when we are born again, but we also gain a new nature that helps us to be Christ-like as the Holy Spirit guides us into all truth (John 16:13).
I just want to encourage and inspire as many people as I can for Jesus Christ.
