Habakkuk 2:3 For still the vision awaits its appointed time; it hastens to the end--it will not lie.
If it seems slow, wait for it; it will surely come;
it will not delay.
Habakkuk 2:4 "Behold, his soul is puffed up;
it is not upright within him,
but the righteous shall live by his faith. (KJV)
We must if we truly believe the Lord, wait on Him, wait on His timing. A true belief doesn't one day say "Ok, it wasn't ever true"...it hangs on through thick and thin because the Holy Spirit within him/her is true and He won't ever let go of His own.
If anyone ever says God is untrue, he/she is deceived, and trying to get others to join him/her in his/her deception. Don't let such a one recruit you into their delusion but hold fast to what the Lord says, through His power, by His Spirit, and prove to yourself that your election is true.
Heb 3:6 but Christ is faithful over God's house as a son. And we are his house if indeed we hold fast our confidence and our boasting in our hope.
Heb 3:7 Therefore, as the Holy Spirit says, "Today, if you hear his voice,
Heb 3:8 do not harden your hearts as in the rebellion, on the day of testing in the wilderness,
Heb 3:9 where your fathers put me to the test and saw my works for forty years.
Heb 3:10 Therefore I was provoked with that generation, and said, 'They always go astray in their heart; they have not known my ways.'
Heb 3:11 As I swore in my wrath, 'They shall not enter my rest.'"
Heb 3:12 Take care, brothers, lest there be in any of you an evil, unbelieving heart, leading you to fall away from the living God.
An evil and unbelieving heart is one that has not been transformed by the Holy Spirit of God, but is still of stony flesh, unyielding to the truth of His word....but the righteous (whom God has made righteous) shall live by faith.
