The fruit of our lips comes from our connection with Messiah Jesus. He is the Vine. We are the branches.
“I am the true vine, and My Father is the keeper of the vineyard. He cuts off every branch in Me that bears no fruit, and every branch that does bear fruit, He prunes to make it even more fruitful. You are already clean because of the word I have spoken to you. Remain in Me, and I will remain in you. Just as no branch can bear fruit by itself unless it remains in the vine, neither can you bear fruit unless you remain in Me.
“I am the vine and you are the branches. The one who remains in Me, and I in him, will bear much fruit. For apart from Me you can do nothing.If anyone does not remain in Me, he is like a branch that is thrown away and withers. Such branches are gathered up, thrown into the fire, and burned. If you remain in Me and My words remain in you, ask whatever you wish, and it will be done for you. This is to My Father’s glory, that you bear much fruit, proving yourselves to be My disciples. John 15:1-8 BSB
God has blessed us with the Spirit and We live according to the Spirit.
The Spirit of God dwells in us and God is Father, Son and Holy Spirit. Think on that and walk in the Spirit.
“But you are not in the flesh but in the Spirit, if it is so that the Spirit of God dwells in you. But if any man doesn’t have the Spirit of Messiah, he is not his. If Messiah is in you, the body is dead because of sin, but the spirit is alive because of righteousness. But if the Spirit of him who raised up Yeshua from the dead dwells in you, he who raised up Messiah Yeshua from the dead will also give life to your mortal bodies through his Spirit who dwells in you. Romans 8:1-11 WMB
The Spirit wells up in our spirit and produces the fruit of the Spirit in us.
”But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control. Against such things there is no law.
“Those who belong to Christ Jesus have crucified the flesh with its passions and desires. Since we live by the Spirit, let us walk in step with the Spirit. Let us not become conceited, provoking and envying one another. Galatians 5:22-25 BSB
Thus, the fruit of our lips glorifies God.
“We have an altar from which those who serve the holy tabernacle have no right to eat. For the bodies of those animals, whose blood is brought into the holy place by the high priest as an offering for sin, are burned outside of the camp.✡ Therefore Yeshua also, that he might sanctify the people through his own blood, suffered outside of the gate. Let’s therefore go out to him outside of the camp, bearing his reproach. For we don’t have here an enduring city, but we seek that which is to come. Through him, then, let’s offer up a sacrifice of praise to God ✡ continually, that is, the fruit of lips which proclaim allegiance to his name. But don’t forget to be doing good and sharing, for with such sacrifices God is well pleased. Hebrews 13:10-16 WMB (Ps 119:108; Is 57:19; Jer 33:11)
