"How to maintain constant relationship with God?"
The best way to develop a constant relationship with God, according to the Bible, is to do three things: read the Bible daily and systematically; pray every day; obey God's word in your daily life. See: Deuteronomy 11:18; 30:14; Joshua 1:8,9; Psalms 1:1-3; 119:11,17 37:30,31; 1 Timothy 3:15-17; 4:14-16. Note the lesson of Daniel in his prayer life and the strength it gave him - Daniel 6:10. Also Matthew 26:41; Luke 22:46; Ephesians 6:18; Colossians 4:2; 1 Peter 4:7. Obedience - 1 Samuel 15:22; Acts 5:29; Romans 6:16. Note especially the words of the Lord Jesus Christ in regard to obedience: John 15:14.
