I cannot destroy what God has done. 'All things work together for good.' (Rom 8:28) Even if it seems as if with my own two hands I have pulled everything apart, God still loves me; 'If he is for us, who can be against us?' (Rom 8:31) (Not even myself!)
I am not God. I may 'roll the dice, but the Lord determines where they fall'. (Proverbs 16:33)
'Who shall bring any charge against God's elect? It is God who justifies. Who is to condemn? Christ Jesus is the one who died-- more than that who was raised-- who is at the right hand of God, who indeed is interceding for us'
I cannot fall out of Christ's love. 'It is finished' (John 19:30) 'There is now no condemnation' (Rom 8:1) 'For I am sure that neither death nor life, nor angels, nor rulers, nor things present, nor things to come--- will be able to separate us from the love of God in Christ Jesus our Lord.' (Rom 8:38)
His grace is sufficient. His love can withstand any attack, including mine. My lack of planning in the present, my failure of success in the future... it can't mess things up.
I am secure in the blood of Jesus.
That's what the cross means. That's why it's called good Friday, because 'it is finished'. My fate is sealed. It cannot be broken. My victory is secure. My hope is everlasting.... And I can't mess it up!!
