Is it true that God would forsake us if we forsake him?

Answer 1

The question puts us on the same level as our Creator. A better question to ask would be:

Is the Creator obligated to fix the creation because it is broken? No. But

12I have spoken to you of earthly things and you do not believe; how then will you believe if I speak of heavenly things? 13No one has ever gone into heaven except the one who came from heaven—the Son of Man.[d] 14Just as Moses lifted up the snake in the desert, so the Son of Man must be lifted up, 15that everyone who believes in him may have eternal life.[e]

16"For God so loved the world that he gave his one and only Son,[f] that whoever believes in him shall not perish but have eternal life. 17For God did not send his Son into the world to condemn the world, but to save the world through him. 18Whoever believes in him is not condemned, but whoever does not believe stands condemned already because he has not believed in the name of God's one and only Son.[g] 19This is the verdict: Light has come into the world, but men loved darkness instead of light because their deeds were evil. 20Everyone who does evil hates the light, and will not come into the light for fear that his deeds will be exposed. 21But whoever lives by the truth comes into the light, so that it may be seen plainly that what he has done has been done through God."[h]

Hope this helps.

Answer 2

Many people have useless faith. "Many" will say, "Lord, Lord," in the day of judgment, but be excluded because of their empty, sham faith (Matt. 7:22-23; 25:11-12). Those who forsake Christ and His church prove that they never really belonged to Him or to His true Body (cf. 1 John 2:19). It is those who "abide in My word," Jesus said, those who hold fast the word, who "are truly disciples of Mine" (John 8:31; cf. 2 Cor. 13:5; 2 John 9). The truly justified and righteous not only are saved by faith but continue to "live by faith" (Heb. 10:38). Obedience and continuous faithfulness mark the redeemed.

Answer 3

No.

God will never forsake us. If at any time (before our death), we turn to God, He (or She) will welcome us. See the parable of the forgiving father (aka the prodigal son).

However God will also respect our free will choices. If we freely choose to be separated from God and the blessed forever then He will, with great sadness, respect our choice.

With love in Christ.
