Romans 11:29 (Amplified Bible)
For God’s gifts and His call are irrevocable. [He never withdraws them when once they are given, and He does not change His mind about those to whom He gives His grace or to whom He sends His call.]
1 Peter 4:10 (Amplified Bible)
As each of you has received a gift (a particular spiritual talent, a gracious divine endowment), employ it for one another as [befits] good trustees of God’s many-sided grace [faithful stewards of the extremely diverse powers and gifts granted to Christians by unmerited favor].
