God will provide for all our needs if we give up everything to follow him

God tells us not to work for earthly food, but for heavenly food (John 6:27), and this command is not without promise. The Lord promises all those who seek the Kingdom of God that He will give them all the necessities on top (Matthew 6:33). He tells us to look at the birds of the air, which do not work, and are fed by God; and at the flowers of the field, which likewise do not work, and are clothed by God; and he tells us that we are worth far more than birds or flowers (Matthew 6:25-30). 

Remember the multiplication of the loaves, when the crowd had been with Jesus for three days in a deserted place, and he gave them food because he had compassion on them (Matthew 15:29-38). Let us remember when Peter asked Jesus if he had to pay tribute, and Jesus answered that for God it was nothing, because everything belongs to God and his children have nothing to pay, but he said to him; so as not to scandalise them, go to the sea and take a fish, and open its mouth, and you will find a statere (currency of the time), take it and give it to them for you and for me (Matthew 17:24-27). 

Let us remember the writings of the old covenant; how God, who is always the same, gave manna to the Hebrews in the desert (Exodus 16), as well as water from the Rock (representing Christ) (Exodus 17:2-6); or how when Elijah withdrew to God during the drought, God sent water in a stream for him, as well as ravens to bring him bread and meat in the morning and evening. Let us remember how he (God) then blessed the widow who had given her last grain to Elijah to feed him. And how he not only filled her house with food during the drought and famine, but also raised her son from the dead by Elijah's hands (1 Kings 17).

There are so many examples I could give, to remind you of the Power and Goodness of this Great God who calls us to come to Him by faith, to surrender our whole lives to Him, without worrying about anything. The Lord promises us that if we put our full trust in him and give up our lives in the world to follow him, he will provide for all our needs. We have nothing to fear, for God is the same as before, he has not changed, and he will bless mightily all who obey him. 

God will not give us the riches of this world, for they have been given to the devil, which is why satan told Jesus in the wilderness, that if he (Jesus) will bow down to him (satan), he (satan) will give him all the riches of the nations, for they belong to him (although everything belongs to God in the deeper sense) (Luke 4:5-8). So what God is telling us is not that he will make us rich people and give us the glory of the world, but rather that if we renounce the world and its glory, the riches, our life in this world (totally), then he will provide for all our needs, because we do not seek earthly things but heavenly things (Matthew 16:24-26) (Luke 14-33) (2 Corinthians 4:18) (1 John 2:15-17) (Hebrews 13:14)

Jesus tells us not to lay up for ourselves treasures on earth, which perish; but to lay up for ourselves treasures in heaven, which are eternal (Matthew 6:19-20). Paul tells us that if we have food and clothing (necessities), that is enough for us (1 Timothy 6:7-10). The Kingdom of God is not food and drink, or clothing, but Joy and Peace, true Love in the presence of the Father; it is fellowship with God and with our like-minded brothers and sisters (Romans 14:17-19). Food and clothing God gives us to meet our needs, without our even asking for them, without our even seeking them; therefore Jesus tells us not to seek these things, for it is the Gentiles who seek them, but we are to seek the Kingdom of God and His righteousness, and all these things will be given to us in addition (Luke 12:29-31).

We, therefore, who do not seek earthly things but heavenly things, should not be afraid to give up everything to follow the Lord, the Great God who will take care of us. There is no one who has left everything to follow the Lord who will not receive a hundredfold in this life, and in the world to come, eternal life (Mark 10:28-30). 

We have a choice to make, between God and the world, but if we are double-hearted, divided in our hearts, mixed up between God and life in this world, lukewarm, then God will vomit us out (Revelation 3:15-16). Let us therefore lay up for ourselves treasures in heaven by working, not to obtain the food that perishes (earthly), but to obtain that which is eternal (heavenly). Where our treasure is, there will our heart be also; as for me, my treasure is in heaven.

Luke 12:32 Do not be afraid, little flock; for it has pleased your Father to give you the kingdom. 33 Sell what you have and give it away as alms; make for yourselves purses that do not wear out, a treasure in heaven that never fails, where thieves do not come, and where the moth does not spoil. 34 For where your treasure is, there will your heart be also.
