But the Lord is faithful, who shall stablish you, and keep you from evil.
2 Thessalonians 3:3 KJV
God is well able to keep us
Now unto him that is able to keep you from falling, and to present you faultless before the presence of his glory with exceeding joy, Jude 1:24 KJV
For thou hast delivered my soul from death: wilt not thou deliver my feet from falling, that I may walk before God in the light of the living?Psalms 56:13 KJV
Now, that is reassuringly.
