Phil 2:12 Therefore, my beloved, as you have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling; (NKJ)
Rom 13:11-14 11 And that, knowing the time, that now it is high time to awake out of sleep: for now is our salvation nearer than when we believed.
12 The night is far spent, the day is at hand: let us therefore cast off the works of darkness, and let us put on the armour of light.
13 Let us walk honestly, as in the day; not in rioting and drunkenness, not in chambering and wantonness, not in strife and envying.
14 But put ye on the Lord Jesus Christ, and make not provision for the flesh, to fulfil the lusts thereof. (KJV)
We choose every day to live whole heartedly for our Lord Jesus Christ. It is His grace that keeps us and strengthens us.
