“For the gifts and the calling of God are irrevocable.” Romans 11:29
In Romans 9-11, Paul is addressing the need of Jews to be delivered from God’s present-day wrath through justification and sanctification. Paul talks about God’s sovereign use of Israel in the past and His temporary setting aside of Israel in the present due to her rejection of His righteousness through faith in the Messiah (9:1-10:4). God chose the nation of Israel to service and blessings for the purpose of sharing those blessings with others. But since they failed (10:5- 11:10), God saw fit to elect another group called the Church (composed largely of Gentiles) to accomplish this task (11:11-25). Fortunately for Israel, because God is gracious He will again return to them and fulfill His promises to them (11:23-32).
The reason Paul is confident that God will return to Israel and fulfill His promises to them is because “the gifts and the calling of God are irrevocable” (11:29;cf. 9:4-5). God will not withdraw His promises from Israel because those promises are irreversible (“irrevocable”). The Lord did not choose Israel for her goodness, and He will not abandon her because of her sinfulness.
Likewise, God promises eternal life as a free gift to all who believe in Jesus Christ (John 3:16; Romans 6:23). Since “the gifts … of God are irrevocable” (Romans 11:29) and eternal life is a “gift of God” (Romans 6:23), then eternal life is “irrevocable.” When a person believes in Christ for His gift of eternal life, it cannot be given back to Godnor taken back by Godno matter how the believer lives because it is irreversible or permanent (John 3:16; 6:35-40; 10:28-29; 11:25-27; Romans 8:31-39; et al.). God did not save us from hell because of our goodness (cf. Ephesians 2:8-9; Titus 3:5-7), and He will not abandon us because of our sinfulness (cf. John 6:37; Hebrews 13:5).
This can be especially difficult for people to believe if they have experienced rejection by a parent. For example, imagine an adopted child being returned to his orphanage because his adoptive parent says he is too difficult or sinful to raise. That adopted child may conclude that God will do the same to him if he does not live up to God’s expectations. I have met many Christians who think that God’s love is like the love of their parents. If they do not measure up to God’s standards, then He will take eternal life away from them.
The truth is God’s love is not conditional or temporary like the love of people. God’s love is unconditional and eternal through Jesus Christ (Jeremiah 31:3; Romans 6:23b; 8:38-39). God accepts us permanently as His children the moment we believe in His Son Who died for our sins on the cross and rose from the dead (cf. John 1:12; I Corinthians 15:3-6; Ephesians 1:6). God guarantees to keep us as His children and never let go of us no matter how troublesome or sinful we may be after we are placed in His family (John 6:37; 10:28-29)! This should lead believers to praise God for the depths of His wisdom and knowledge (Romans 11:33-36)!!!
