‘Fulfil your vows’ (1:15). God is calling us to be faithful to Him. We are to be faithful in worship. We are to be faithful in reading His Word. We are to be faithful in prayer. We are to be faithful in giving. We are to be faithful in witness. Our faith is to be real. Our faith is to make a difference. It’s to change the way we live. It’s not to be a case of ‘faith without works’. That kind of ‘faith’ is ‘dead’ (James 2:17). Our whole life is to be a life of faith. It is to be a life of ‘love’. We are to live ‘for the glory of God’ (Romans 14:23; 1 Corinthians 16:14; 10:31). ‘Fill Thou our life, O Lord our God, in every part with praise... Not for the lip of praise alone, nor even the praising heart we ask, but for a life made up of praise in every part’ (Church Hymnary, 457).
To those who refuse to live in obedience to Him, God speaks His Word of judgment: ‘I am against you’ (2:13; 3:5). Those who refuse to listen to God’s Word of salvation - ‘The Lord is good, a refuge in times of trouble. He cares for those who trust in Him’ - will hear a very different Word from the Lord. It will be a Word of judgment. God’s Word will come like ‘an overwhelming flood’: ‘He will pursue His foes into darkness’ (1:7-8). None of us needs to face this ‘overwhelming flood’ and hear the words, ‘I am against you’. Each of us can come to Christ and hear His Word of ‘overwhelming victory’: ‘If God is for us, who can be against us?... Nothing will be able to separate us from the love of God in Christ Jesus our Lord’ (Romans 8:31,37-39).
