Please continue with this chapter as this one verse is not to be read alone for argument's sake.
Jeremiah 29:10-14 (NKJV)--The truth is that you will be in Babylon for 70 years.BUT then I will come and do for you ALL of the GOOD things I have PROMISED.
For I know the plans I have for you, says the Lord."They are plans for good and not for disaster", to give you a future and hope. IN THOSE DAYS WHEN YOU PRAY I WILL LISTEN. IF YOU LOOK FOR ME IN EARNEST, you WILL find me when you seek me". "I will be found by you", says the Lord. "I will end your captivity and restore your fortunes. I will gather you out of the nations where I sent you and bring you home again to your own land".
God has a plan, or a will for His people. Notice again though that those people MUST SEEK HIM first with sincerity for that plan to be executed. He will NOT force His will upon us. If you can provide scriptural evidence stating that He does force His will upon us please provide it so that I may study it for myself.
This scripture is not in isolation..there are conditions for God to hear prayer. some would argue that in fact in Chapter one the call on Jeremiah was made clear
5 Before I formed thee in the belly I knew thee; and before thou camest forth out of the womb I sanctified thee, and I ordained thee a prophet unto the nations.
Some would argue that was set aside by God from before his birth.
But there is added a promise, that God would hear them. It may however appear, that God promised conversion even in the first clause; and, no doubt, prayer is the fruit of repentance, for it proceeds from faith; and repentance is the gift of God. And further, we cannot call on God rightly and sincerely except by the guidance and teaching of the Holy Spirit; for he it is who not only dictates our words, but also creates groanings in our hearts. And thus Augustin, writing against the Pelagians, understands the passage, and proves that it is not in the power of man either to convert himself or to pray; "for God," he says, "would in vain promise what is in the power of man to do; and this is the promise, ye shall pray; it then follows, that we do not pray through the impulse of our own flesh, but when the Holy Spirit directs our hearts.(Calvin commentary)
